Applescript to run javascript

Hi all,

I got error in this script. Could anyone help on this?

tell application "Finder"

    activate

    set myApps to {"CS3", "CS4", "CS5"}

    set selectedApp to choose from list myApps with prompt "Choose Application:" with title "Launch Application"

    if the result is not false then

        set myApp to "Adobe InDesign " & selectedApp

        display dialog myApp

        set myFile to "Applications:" & myApp & ":Scripts:Scripts Panel:Sample.jsx"

        tell my application myApp

            activate

            run script file myFile   // error "Adobe InDesign CS4 got an error: A unknown token can’t go after this “)”." number -2740

        end tell

    end if

end tell

Regards
