Yea, I was wonderin' what to put here:

Function freeze(%sender,%target_nm)
{
if(!ClientIsAdmin(%sender,"/f command failed you are not admin"))
return;

%match = matchClientName(%target_nm);
%client = firstword(%match);
%status_msg = restWords(%match);

If(%client == -1)
{
schedule(1000,false,"CommandToClient",%sender,'CenterPrint',%status_msg,4,4);
return;
}
schedule(1000,false,"centerprintall", %client.nameBase SPC $pref::Server::freezeMessage ,4);

 

 

}

I already found an easier way to freeze but I need to know how to do it this way. :[
