Found it...I put $curentkey instead of $currentkey -_-

PHP Code:
if ($curentkey != $cookie){
echo 
'<td>&nbsp;<input type="checkbox" name="add[]" value="' $key '"></td>';
}else{
echo
'<td></td>';
}} 
$currentkey = 1$zfPq0JLHl/g
$cookie = 1$zfPq0JLHl/g

But I'm still getting the checkbox line...
why?
Hopefully its something really simple that I'm just not seeing....
