[FX.php List] Checkbox

[Rob H. Christensen]

I have some checkboxes, which can have multiple values. How do I show the
checked boxes on the page?

I have tried this:
<?PHP
$TRK=$Data['Trykkeri'][0];
foreach($Vis2ListResult['valueLists']['Trykkeri'] as $key=>$value){
            if($TRK==$value){ $Select="checked";}else{$Select="";} ?>
            <input type="checkbox" name="Trykkeri" value="<?PHP echo $value;
?>""<?PHP echo $Select;?>"><?PHP echo $value;
            }?>

This shows the checked box as long as there is only one checked. As soon as
more options are checked, it only shows empty checkboxes.

$TRK is an array, which correctly displays the checked boxes.

Any suggestions?
