Attempt to index local 'v' (a nil value) - lua

Question

I'm trying to edit a lua script to add on my Garry's Mod Server, but I get this error and I dont know what to do.
Error:

Answer 1

This is because
table.Random(self.itempoints)
returns nil. Did you mean math.random? If you post code for that table.Random func I can give more info.
