[Plugin: Allow PHP in Posts and Pages] will not work with for loop

It took me very long to figure it out (by installing another plugin, shortcode exec php), but for some reason it is not able do deal with for for loops…

Start of my code up to were it broke:

$answers = array (
	"A" => "XX",
	"B" => "YY",
	"C" => "ZZ",
	"D" => "WW",
	"E" => "UU"
	);
$questions = $_GET["q"];
//Only run if we get the q(uestions) parameter
if ( $questions > 0 ) {
	for ($i	= 1; $i <= $questions; $i++) {

		$responses = $_GET[$i][0];
		}
	//Return array

The code would throw an eval error right after for ($i = 1; saying it was missing a ;. 🙁
