Hi,

I’m making a tool for users to enter the filename of a video in an input box. From here the users click a “next screen” button. I’m trying to write some code that will verify if the filename provided will actually find a video on the user’s system. I’ve been trying to load the file into an empty movie clip, and I can get it to load ok. My problem is, I’m having trouble writing a catch statement when the movie ISN’T found. Is there a better way of doing this? I tried using .onData event handlers to see whether or not this could be my control statement, but I haven’t figured it out yet. Any bright ideas? :h:  
Thanks
