To make the File Manager "idiot" proof, I'd like to add a choose button at the top next to the drop down box.

If your immediate response to this is "why?", please re-read the first paragraph. Moving on...

I've found where in the code I need insert the button. I have come up with the code below, but I still can't figure out what other values I need to actually make it function as a "choose" button.



Any help is much appreciated. Thank you.
