probsoln package FAQ

Label ... undefined 🔗

You need to define a problem before you can use it. Check to make sure you haven’t mis-spelt it, and check to make sure you have used the file in which it is defined either via \input, \loadallproblems or \loadselectedproblems. If you have used \loadrandomproblems, you shouldn’t try referencing a problem since there’s a chance it may not have been selected.
