# numbering of tcolorbox

I have a series of tcolorboxes, and i used the \thetcbcounter to number them (they represent different stages of a project).

The thing is, it automatically numbers like this 1.1, 1.2, 1.3 and so on, but I want them to be numbered 1, 2, 3, etc. is there a special argument I have to add on \thetcbcounter to get it that way?

Thanks

This is what it looks like with the pictures

• We really need a complete example. I did this for the first time the other day and mine came out Case 1, Case 2, Case 3 etc. as I expected. ('Case' being text added prior to the use of the counter in the title of the box.) And the cross-references cam out as 1, 2, 3 etc. again as expected. – cfr Feb 2 '16 at 2:08
• Normally, I'd assume the difference might be that you are using book and me article or something. But I'm not. I'm using book. Although I do not, strictly speaking, have chapters but only chapter-like things. Still, I have sections. So if it defaults to numbering-within for you, I'm not clear why it doesn't do so for me. Presumably, you are doing something in your code differently from me. But I have no idea what as you've not shared the code. – cfr Feb 2 '16 at 2:13

You have number within=section which numbers the boxes within the section, prepending the section number.
Delete number within=section and the boxes should be numbered with a simple counter.
