Duplicate selected item and rename in a script.

I made this little applescript to use in Finder, however I would like it to work within Adobe Bridge, but I have discovered it does use applescript.

To explain what the script.

Get selected Item

Duplicate

Prompt for new file name

Rename original image to "result of input text"

Prompt for new file name (silver)

Rename original image to "result of input text" & "_Silver"

If required Prompt for new file name (Rose Gold)

Duplicate file and Rename original image to "result of input text" & "_Rose"

I hope that makes sense and I hope someone can help me translate this to Javascript for Bridge.

Many Thanks

Matt
