Noobie - script trying to open classic when it's not needed

Question

I need some help. I have written a short, simple script that I hope will work to open an index.htm file in a users default browser when it is run from a cd. I have a disk that basically contains a website with links on the disc and links to the web. Of course in windows I am using autorun to start the index file, but for Mac I am opening a finder window with an icon for this script so that the user has a clean interface and does not have to search for the index file.
The problem is that after compiling and testing my script it works fine, but when I save it as an app it tries to open Classic everytime. I don't want it to do this. This is for OS X only and it should be opening the file in Safari or Firefox so there is no need for classic.
In the Save As dialog box there is no check box to require classic it just automatically saves it that way. When I click on the saved app and choose "get info" is gives the filetype as "Application (classic)"
I am using Script Editor 2.1.1.
Here's the script:
try
tell application "Finder"
open file "BIB_5113:index.htm"
end tell
on error
beep
display dialog "Oops: " & "Please Insert your course CD and try again. " buttons {"OK"} default button 1
end try
Can someone please help, I have searched here, googled and posted at the MacScripter forums with no luck.
Thanks for your help.

Answer 1

OK, update - By saving as "Application Bundle" I now have the script working, somewhat. Now I need to know if and how I can get the script to see an invisable file. I am using Toast 7 to burn a Mac/PC disc and I have all of the files hidden. The script runs but it does not find the index.htm file.
Can anyone help?
Thanks
