If you have a script runtime error, this cannot be fixed with getting dvars from clients. However, we can help you solve the error, but you must post it and the code so we can see where the problem is.
Golden Rule - if you have an error you don't understand, don't try to figure it out yourself. Post it here for us to look at. We are pretty damn good at this stuff, and I doubt there is an error we couldn't fix.
