I'm trying to make a group system, and I've got a problem with the line that checks if a user is in a group or not. (/joingroup)

These are the errors:

Code:

C:\Users\Damien\Desktop\samp server 0.3\filterscripts\sffradmin.pwn(302) : error 029: invalid expression, assumed zero
C:\Users\Damien\Desktop\samp server 0.3\filterscripts\sffradmin.pwn(302) : warning 215: expression has no effect
C:\Users\Damien\Desktop\samp server 0.3\filterscripts\sffradmin.pwn(302) : error 001: expected token: ";", but found ")"
C:\Users\Damien\Desktop\samp server 0.3\filterscripts\sffradmin.pwn(302) : error 029: invalid expression, assumed zero
C:\Users\Damien\Desktop\samp server 0.3\filterscripts\sffradmin.pwn(302) : fatal error 107: too many error messages on one line

Here's the code:

Can't seem to figure out why I'm getting this..
