To include numbering prefixes from higher levels, enter text or click at the start of the Number box and choose Insert Number Placeholder and then select a Level option (for example, Level 1), or enter ^ and then the list level (for example, enter ^1). In a list with first levels numbered 1, 2, 3, and so on, and second levels numbered a, b, c, and so on, including the first-level prefix in the second level renders second-level numbers as 1a, 1b, 1c; 2a, 2b, 2c; 3a, 3b, 3c.
You will occasionally want to place an unnumbered paragraph in the middle of a sequence, but the moment you hit Enter, another paragraph number pops up. To fix this, toggle paragraph numbering off by pressing the paragraph numbering button you used for the previous paragraph. (If you use the button’s drop-down, choose None as the numbering scheme.) Unfortunately, the paragraph settings won’t revert to Normal here; it’ll usually have the paragraph indented 0.25. Use the keyboard shortcut CTRL+Q to strip paragraph settings out, then revise the formatting as you wish. numbering in coreldraw

This feature is easiest to use when you combine it with Word's built-in heading styles. However, you can map a custom heading style to the multilevel numbering feature—it just takes more work. Word handles nine levels, but any document with more than four levels should receive a serious developmental edit. More than four becomes confusing and perhaps worse, unreadable.
Hi Enas, it sounds like the issue you are experiencing is about the PDF Export process. Have a look at this thread on the Adobe Community support forum: It seems to suggest that corrupt image files can cause problems like this. You also might want to check that you enough space on the disk you’re exporting the PDF too – if it runs out of room then you would get errors. Sorry I can’t help much more than give you some general ideas. Best of luck resolving the issue. Cheers Philippa
In summary, paragraph numbering is really just an exercise in logic, and this blog post is showing the numbering styles for a very specific project. Your project may be similar, but not exactly the same. You just need to think though the levels and how you want to restart the numbers. I do my best to think it through correctly the first time, set it up, and then try as hard as I can to break it, so that I can find my errors. The good news is that once you get your numbers working, you shouldn’t ever have to think about it again.
One of the harder things to do in Adobe InDesign, surprisingly for a page layout tool, is to create multilevel or outline format numbered lists.  The right way to accomplish this, according to the folks at Adobe, is to create a Style for every level of the list you’d like to have! Here are Adobe’s instructions on how to do so (This content is taken directly from
Roger Wambolt, senior product trainer at Corel, eases in with an exploration of the interface and touches on the major players in the toolbox: the Pick, Shape, Crop, Curve, and Interactive tools. Then, once you know how to draw simple lines and shapes, he shows how to group, copy, and adjust objects on your document page. Plus, learn about working with text, using the new Font Manager and the extensive library of fonts in CorelDRAW, adding and editing images, automating tasks with scripts and macros, creating color palettes, and preparing your CorelDRAW projects for print. Roger closes with some tips on customizing the CorelDRAW interface to be more productive and create your designs in fewer steps.

So I spent some time trying to figure it out, playing with Normal.dotm and the various styles (List paragraph, List Number, List Bullet etc etc). And finally, when I've got Normal.dotm open (i.e. I'm editing that template file), I get my result: I apply a standard numbered list, and it comes up flush left (i.e. not indented) and hanging at 1.0cm (cos I don't use inches...) and with a tab stop applied at 1.0cm as well - funky stuff!
We use the auto page numbering trick here, the trick is to do it as spreads. You just make your pages the same size as the ticket with crops and bleeds. Then set up the shell on the master page and place your auto page number where you want your numbers. Each pages is the next number. You can also have two sets of numbers for perforated ticket. You then can use the page start options to add to the numbers and keep the same number of total numbers. For example you would do a new page start after number 99. 0001 to 0099 so it doesn't add two "0's" to the front of 100 and you get 00100 when you want 0100. Works great for small quantities, we have done up to 1000+ tickets and once you do it once or twice it is a snap to set up. To avoid having to do 1000 pages just send the tickets in groups. Usually between 25 to 100 at a time works good depending on artwork file size. Just save each time before sending to printer and name the file with what the tickets are. Like "MyTickets-0001-0100.Indd". Makes it easier to go back if you have a problem. You can even do two rolls of tickets if your using 12 x 18 sheets by flipping the sheet and doing one row along the top and one along the bottom on reverse side. That is if your ticket is single Sided. Two sided tickets are a bit trickier. :-)

Changing the numbering display affects how pages are indicated in the InDesign document, as in the Pages panel and in the page box at the bottom of a document window. The numbering display also affects how you specify page ranges when printing and exporting the document. However, the numbering display does not change the appearance of page numbers on document pages. numbering in indesign
