Cannot get my array from my form right

PHP
,

Sorry for the late reply, but I have notices some issues.
If I take away the <?php echo $; ?> I will get the following array which doesn’t make any sense :

array(1) {
  [4]=>
  array(1) {
    ["aantal_keer"]=>
    string(1) "2"
  }
}

So a problem now is, where is my file out of the sudden ?
I changed the checkbox to a input hidden with the filepath+name as value.
But it doesn’t get posted trough which is weird.
