Right, got it. So do you understand, now, that the basis of your script not working is the conditions used? In your first script, if $2- is $null/$false/0, the condition is met straight away and the command associated with it is reached (i.e., goto b)... If that condition fails, then the script tries the other condition. In your second script however, because of the way that condition is interpreted, $2- can be $null/$false/0 so long as $nick == %SUPERADMIN, so the script may well not reach the other condition.
