Omitting Useless Code???

[nxchew]

ok guys... here's my next problem, I finally got around to using an array like you said, and got my variables printed when they're in the array and selected from my reffering page... but now, I need to omit alot of text on my order.php because out of about a hundred options, they can only have a few selected... so I end up getting something like this...

<input type='hidden' name='1' value='3d studio max'> <-- selected from list.php
<input type='hidden' name='2' value='Adobe Photoshop 7'> <-- selected from list.php
<input type='hidden' name='3' value=''> <-- not selected from list.php

Somehow I would like to not even print line three. here's how I'm printing it also.

for ($i=0; $i < count($appname); $i++)
{
echo"<input type='hidden' name='{$id[$i]}' value='${$appname[$i]}'>";
}
?>

and here's a sample of my array
$appname = array('appname001', 'appname002', 'appname003', 'appname004' all the way to appname400.

Thanks in advance for all the help!

Ok.. After many attempts my parnter and I came up with the answer..

for ($i=0; $i < count($appname); $i++)
{
if (${$appname[$i]} != ""){
echo"<input type='hidden' name='{$id[$i]}' value='${$appname[$i]}'>";
}
}
