HELP!! Simple script won't work.....

The simple script below works fine in Tiger and also in OSX 10.2.8, but when it’s run on Panther (10.3.7) on 3 different machines, it comes up with the same error. The error:

“Some data was the wrong type”

The script:

tell application “Finder”
activate
open location “http://www.giggles.net
end tell

Does anyone know why?? I essentially need a script that will work on all versions of OS X that will open the designated URL in the system’s default web browser. Is there a better way to do it that would be more compatible?

Nevermind, someone on another board pointed out my flaw. I was WAY overthinking the problem and the solution was as simple as removing 3 of the lines and making the script just the one line:

open location “http://www.giggles.net
