          echo "<TD><A HREF=\"$val\" CLASS=\"menu\">$key</A></TD>\n";

(isn't $val here an array of bike models? If so you'll end up with <A HREF="[Array]" ...>)

        while (list($sub_key, $sub_val) = each($val)) {
            echo "<TD><A HREF=\"$sub_val\"

CLASS=\"menu\">$sub_key</a></td>\n";

        }
    }

} Are you looking for something more like this:

$modelString = ""; $makeString = ""; foreach($bikes['Road'] as $make => $models) { $makeString .= " " . $make; foreach($models as $model => $link) { $modelString .= "<A HREF=\"$link\" CLASS=\"menu\">$model</A>"; } } print($makeString . "<br>\n"); print($modelString . "<br>\n"); (I don't get what you're trying to do with the table, though) -Steve

Will produce: Trek Trek 5200 LeMond Zurich Chambery Alpe d'Huez BuenosAries Tourmalet Moots VaMoots as it should... But, I need it to produce: Trek LeMond Moots Trek 5200 Zurich Chambery Alpe d'Huez BuenosAries Tourmalet VaMoots And I need to get the value of $sub_val in the nested "while" loop to where $val is in the outer loop. I'm really stuck, any suggestions?? -Brian **************

The script is still working right, you just need to nest another while loop into your current while loop. Like so ... if ($cat == 'bikes' && $sub_cat != 'Road') {

      while (list($val, $key)=each($bikes[$sub_cat])) {

echo "<tr><td>$val</td>"; while (list($sub_val, $sub_key) = each($key)) {

          echo "<TD><IMG SRC=\"images/spacer.gif\" WIDTH=\"25\"

HEIGHT=\"1\" ALT=\"\" BORDER=\"0\"></td>\n";

          echo "<TD><A HREF=\"$sub_key\"

CLASS=\"menu\">$sub_val</a></td>\n"; } } } alternatively, if you know specifically what you want you could do this ... if ($cat == 'bikes' && $sub_cat != 'Road') {

      while (list($val, $key)=each($bikes[$sub_cat]["Trek"])) {

          echo "<TD><IMG SRC=\"images/spacer.gif\" WIDTH=\"25\"

HEIGHT=\"1\" ALT=\"\" BORDER=\"0\"></td>\n";

          echo "<TD><A HREF=\"$key\" CLASS=\"menu\">$val</a></td>\n";

} }

No, all that will do is reverse the placement of the values. So now it prints out Array and puts the item in the URL. Still the same problem.

I'm stuck. $key returns "Array" how can I get at each level of this array? if ($cat == 'bikes' && $sub_cat != 'Road') {

    while (list($val, $key)=each($bikes[$sub_cat])) {
        echo "<TD><IMG SRC=\"images/spacer.gif\" WIDTH=\"25\"

HEIGHT=\"1\"

ALT=\"\" BORDER=\"0\"></TD>\n";

        echo "<TD><A HREF=\"$key\" CLASS=\"menu\">$val</A></TD>\n";
