How can I do something like this in the same while statement. This does not work while (list(,$possible) = each($possiblefields) list(,$possibleview) = each($possiblefieldsdiscription)){ }

What about using && ? while (list(,$possible) = each($possiblefields) && list(,$possibleview) = each($possiblefieldsdiscription)){ } Doesn't && mean if both variables are TRUE.

Yes, isn't that what you wanted? Normaly a while checks also if it was TRUE. now it checks if both are TRUE.. If you only require one of both to be TRUE, use || instead of &&. I am trying to fill in the drop down box in the script below but it is not working it is only giving me the $possibleview data but not the $possible data $fieldnumber = 0;

            while (list(,$field) = each($fields)){
                echo "    <TR>\n";
                echo "        <TD><SELECT NAME=fieldorder[]>\n";
                reset($possiblefields);

reset($possiblefieldsdiscription);

                $anyselected = '';
                while (list(,$possible) = each($possiblefields)&&

list(,$possibleview) = each($possiblefieldsdiscription)){

				                         $selected = @(($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++;
            }

Ok, not sure about where you are pulling/representing some of your data, but here is what I came up with in-place of your code. foreach( $fields AS $field ){

	echo "    <TR>\n";
	echo "        <TD><SELECT NAME=fieldorder[]>\n";

for( $i=0; $i<count($possiblefields); $i++ ) { $possible = (isset($possiblefields[$i]) ? $possiblefields[$i] : 'NOT_SET'); $possibleview = (isset($possiblefieldsdiscription[$i]) ? $possiblefieldsdiscription[$i] : 'NOT_SET'); if ( isset($fieldorder[$fieldnumber]) && $fieldorder[$fieldnumber] == $possible ) { $sel = 'selected="selected"'; } else { $sel = ''; } echo "<OPTION value=\"{$possible}\" {$sel}>{$possibleview}</OPTION>\n"; }

	echo "        </SELECT></TD>\n";
	echo "        <TD>{$field}</TD>\n";
	echo "    </TR>\n";

} Give it a try and let us know Jim Lucas
