If you've got more than one line of Python then you should probably define a 
normal Python function (just use "def" as you would in a normal python script 
- there are plenty of examples of this) and then call this using ${@...}.

I think you just need to get the value of the FILE variable e.g

 d.getVar('FILE', True)
