Perhaps you could try this...

[PHP]
if (isset($var)) {

Do what you don't want to do here...

} else {
Do what you want here
}[/PHP]

The isset() function returns a boolean. So it is either true or false.

When you test using if (isset(xxx)) your action is performed on the true result of the isset.
When you test using if (!isset(xxx)) your action follows the true result of the NOT isset.

Hope this is clear. So the answer is: test with !isset(xx)
