Hello, I made a weapon for gmod ttt but this weapon is too powerful, I searched for forums but nobody gave a solution of how to make a weapon cost 2 or more credits but nobody gave it, someone at this time knows how?

I found code for that on this forum a while ago and saved it for future use. I tested it and it does work:
