In script 1, I'm guessing cs_exp[vid] is the nil value. It's because you didn't define its value or vid must be 0 or more than 32. In script 2, I can't really tell but since you already defined sd.damage from index 1 to 32 with initArray function, src must be 0 or more than 32.

You dont have to declare parameters as local/global. They are local already.

Replace "> 0" part with this below. Should work.

if player(id,"usgn") == true then

Value of "usgn" in cs2d lua cmd

player is not U.S.G.N. ID anymore? Maybe a bug, or you replace it with yours. Well if you use user

GeoB99's code there will be another error because player(id, "usgn") returns boolean value and you can't concatenate a boolean value while in user

Cure Pikachu's code at line 3, it's attempting to concatenate a boolean value.

The usgn property of a player should be a number in all cases except when a player doesn't exist, in which case it returns false. Fixing it to user

GeoB99's suggestion is just duct tape on a sinking ship - it might not return errors that way, but it will likely result in unexpected behaviour.

Your problem is that even though you supply an id parameter to the SaveUser function, you still have a for id = 1, 32 do loop surrounding your actual saving code. Get rid of it and it should work all right.

In all honestly, the whole script could do with a rework, with lines of code like if player == exist then.
