I've had this happen when I do use the type="submit", and on the 
receiving end, my php is looking for "if ($submit) {"

Since submit was never pressed, the if statement doesn't work out to true.

So you can get around it by having an <input type="hidden" name="foo" 
value="1"> and then on the receiving end you do "if ($foo) "

And it works out to true whether they hit submit button or not.
