Does anyone know how to include chapter number in TOC?

Question

I have a book project which inclueds a couple of indesign documents, I already inserted "chapter number" as text variables in the page numbering, something like "1-1". In this way, I didn't put section prefix in the  "numbering & section options". However, when I update my TOC, it doesn't show the chapter number "1-". Is ther any way I can include that but not manually put figures into the "section prefix"?

OK, looking at the file I can't see any way to make this work the way you'd like. The TOC can only use the text inthe paragraph being picked up, text you enter as a separator, and the page number marker and optionally it's prefix.
HOWEVER, it can, I think be made to work by adding the tab to the headings, followed by the chapter number variable and the hyphen. You need to add a character style that changes the character color to "None" and use it as a nested style in your heading paragraph styles (DO NOT APPLY IT DIRECTLY) as [None] through the tab, then the colorless character style through 1 sentence.
I don't see why you couldn't add the required text to the headings using a GREP Find/Change. I did it by entering the tab, variable and hyphen in a frame then copying to the clipboard and using the following GREP
Find: .$ (that's the last character in a paragraph)
Change: $0~C ($0 is the found text and ~C is unformatted content of the clipboard).
You'll have to run this for every paragraph style that you want to include in the TOC, and you'll have to remove the tab character you've specified now between the entry and the number in the TOC dialog.
