You can't do something like that. Do it like -

pawn Код:

var += 4;

EDIT:A bit late.

Has no effect, that's a sum but you do nothing with the result. It's like doing:

pawn Код:

8 + 4;

That doesn't change the value of 8, it just creates s new number, but nowhere do you store that new number.

O.... I understand now. Thanks for the explanation.
