Hmm strange, i don't see any real error, so to test if it's a problem with
the while loop, you could assign the backward order. So the code would look
like the one below. Please test it, and see if you still get the same
problem, or if you get $possible now instead of $possibleview.

$fieldnumber = 0;

echo " <TR>\n";
echo " <TD><SELECT NAME=fieldorder[]>\n";
reset($possiblefields);
reset($possiblefieldsdiscription);
$anyselected = '';
while (list(,$possibleview) =
each($possiblefieldsdiscription) && list(,$possible) =
each($possiblefields)){
$selected = @(($fieldorder[$fieldnumber] == $possible) ?
'SELECTED' : '');
if ($fieldnumber >= count($fieldorder) && !$anyselected){
$selected = 'SELECTED';
}
echo "<OPTION value=\"$possible\"
$selected>$possibleview</OPTION>\n";
}
echo " </SELECT></TD>\n";
echo " <TD>$field</TD>\n";
echo " </TR>\n";
$fieldnumber++;
}
It now passes the $possible fields but not the $possibleview so it is
picking up the last list but not the first
I also tried it with || and it does the same thing
