First off, I know nothing about PHP other than the fact that it starts with a <?php and ends with a ?>. We all have to start from somewhere, right?
I inserted some PHP code called Upload2Server at the top of my page that's going to be an application form. The user fills it in and what I'm trying to do is simply email all the fields to the client.
The code looks really nice

, but this statement:
if($size > 0)
Makes my browser think it's the end of a tag and from that point on, all the PHP code is displayed at the top of my page.
Is there a suitable substitute for "if($size > 0)"?
