mapping a net share

i made an applescript app for someone in the office to be able to map a net share when they need it...often times they do not use it or they are mobile and not always connected to the lan...problem is that the applescript.app on her machine tries to launch in classic, only to say "Classic is not installed". we have 2 other machines in the office not running classic (They are running 10.4.11) and can run the app fine...any ideas...thanks
