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 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. Tijnema

$fieldnumber = 0;

          while (list(,$field) = each($fields)){
              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++;
          }
