PHP Code:

You should check if victim is valid
Edit: Check IsClientConnected before IsClientInGame

[climbw34468]

what does it mean
if (!victim)

[Silvers]

Player indexes start from 1 and not 0 so you must check for this.

if (!victim) is the same as if (victim == 0) and
if (victim) is the same as if (victim != 0).
They will all evaluate to true. Any other number would evaluate the statement to false.

I forgot the ! before IsClientInGame and IsClientConnected... sorry I always do that by mistake
