Allright, it worked. Thanks! But, I've never had problem with this one, I even know, that it needs to be there, because sometimes the menues fu*k up and choose random item, if this check is not there. Strange... Can someone explain something more about this problem?
EDIT: To response on nicko's post. Allright, after I read up all the sh*t about these loops, I've decided, that I will folow exolent's method. Because in one thread, he explained something like this is the best way, but I couldn find it right now. So, is this really the best way and is there any better way to loop trough all connnected players on the moment?
