Why is it highly inefficient? I don't get that part.

What I do is have a "mode" for each stage.

The mode would be undef on first loading the page. Submitting the form would include a hidden field or whatever that said "mode is now 'secondstage'" and so on.

So the code ends up being two or three large blocks like this: 

if($mode eq ''){
  # stuff that happens on the first page
}

if($mode eq 'secondstage'){
  # stuff that happens after the upload
}

if($mode eq 'finalstage'){
  # stuff that happens after their secondstage input
}

if($mode eq 'finished'){
  print "Thanks, we're done.";
}
