Actually in this instance the if statement is checking to see if the variable is not set. So if the form has not been submitted then the form will be displayed. Similar to what you said but slightly different. :)

PHP Code:


			
if (isset($variable)) //if the variable is set
if (!isset($variable)) //if the variable isn't set

Hope that helps :)

Edit: Yeah, sorry what you said, mis-read it.
