Array scanning stops by itself before reaching the end.

I got this stupid problem: I create an HTML list of inputs: <input name="Answer[]" type='checkbox'> that stretches to some 25 elements. When I try to read the values ("on" or "off") with the code below, PHP won't read past the 8th. element and says it's found an undefined variable (which is $x). No matter what I do, it's always the 8th. element. for($x = 1; $x <= ($TotalAnswers); $x++) { echo($Answer[$x]); } Anyone has a prompt solution? I'm getting desperate. Thanks, Pepinho.
