1. (not positive on this point so correct me if I'm wrong) you shouldn't
compare with !==. Instead us !=.
2. What does the following do?
for ($i=1; $i<=$entries; $i++)
{
if(empty($_POST["resolutions".$i]))
{
echo "empty!";
}
else
{
echo "not empty!"
}
}
You might also like to try isset() along with empty().
