Forums Scripts & Popups $null, $exists and if file is loaded.

if $script($3) {
unload blablabla.
msg blablabla.
}

should be sufficient

for trying to load a script you will still
need to use the $exists identifier since
$script would of course return $null for
not loaded but will not tell you if the file
exist to make sure you are loading a valid file
of course you may want to do both.. first check
to see if loaded using $script and then load if
$exists
