Read variable before assigned

I have a tabularx environment, with the first column containing each line number. This number is incremented automatically thanks to a variable:

\newcounter{versionscnt}

and then for each line:

\addtocounter{versionscnt}{1} \theversionscnt

This works perfectly fine.

But now I would need to print the total number of lines (ie the last value of my counter) BEFORE the tabularx. Is there a way for me to do that?

Thanks a lot for your time.

PS: I found some really long solutions on this forum, for related issues, but 1) I did not understand them and 2) I don't think that this requires 50 lines of code (but I might be wrong, I don't know)...

Please provide a minimal working example (MWE) that shows how you currently use your counter in the tabularx environment. Testing ideas is a lot easier then. – leandriis Sep 06 '20 at 16:44

How to display the final value of a counter at the beginning of a document? could be related. – leandriis Sep 06 '20 at 16:45
