It looks like you haven't cut-and-pasted - for example, you should have

.. elsif (defined param ('file_chosen'))

.. but obviously, you don't, otherwise it probably wouldn't even parse. The other one ought to be something like

 elsif (defined param ("$temp_name"))

(personally, I prefer double quotes, most don't.)

I think you ought to try and post the actual code, rather than a pseudocode example, as there are lots of other things wrong with this which look more like someone trying to express what they want to do rather than the code they already have.
