Problems with revcopyfile

[Jonathan Kotthoff]

This does not seem like it should be this hard...I must be missing  
something...i am running 2.7 making a simple stack that will copy a  
file to a target on Winows XP and Mac OS X.4...

here is the code:

on mouseUp
   -- bring up a standard system "save as" file selector

   ask file "Save file as:"
-- if the user cancels, exit without saving
   if it is empty then exit mouseUp
   -- put it into filePath
   put it into filePath
-- Copy file
  revCopyFile "/Content/rubyonrails.pdf",filePath
end mouseUp

no file is copied to the target folder however...

anybody have an example of a stack that copies or an explanation

Thanks in advance...
