Sorry if we seem to be coming off as harsh, but you have to realize that we end up with many complaints about problems with little or no additional information. If we do manage to get any information it is usually after asking multiple times, and then a large majority of these problems turn out to be caused by some other addon which the person has.
I'm not trying to say you don't have a problem, but when we, and others, are running it without problem then there must be some other variable involved which we don't know about, and thus can't do anything to fix.
Please go back and check for any errors in console, and list all other addons/scripts you have installed on your server. Without this information there is no way we will be able to help you.
Also, I would like to point out that you are infact not having the same problem as the OP. His/her problem was simply that they didn't want everyone with slap access to be able to use the phys gun on players.
I hope we can solve your problem, but in order to do so you need to help us help you.
