I wanted to make the counter for a theorem displayed as capital roman numerals (I, II, III), but none of these attempts worked


Is there a way to do this?

    Welcome to TeX.SX! Please help us to help you and add a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}.

Simply use:


Defining a new theorem environment test defines a new counter test. The optional argument, such as you used, says the ‘test’ environment shares the counter of another theorem-like environment.
