Ah, I think I see....
So, when I put that <?php TestPhp();?> inside the action= quotes, I'm
not calling the function as a result of the action click, we're just
inserting whatever text that function returns into the 'action'
parameter at the time the 'action' item is first parsed - is that right?
Thanks for the insight
