RE: passing array values in forms

This is a variation to similar string earlier. Have been checking books, online manuals, suggestions here - tutorials and such. Having issues passing arrays in forms. I have been working on this a few days and am stuck. Am trying to pass cat[] and id[] with whatever checkbox user checks. cat[] works fine. My id[] is hidden and am not able to pass correctly. cat[] will display correct item on second page but idid[] just passes 12 (which is the number of initial items in the result from query) - or it will display 1,2,3,4,5,6,7,8,9,10,11. Does anyone have suggestions. I have tried using submit hidden value among other variations...to no avail. Thx Mignon <CODE BEGINS> page1.php snipet <form action="comp_page4.php" method="post"> <? for($knt = 0;$row = mysql_fetch_row($res); $knt++) { echo "<tr><td><input type=\"checkbox\" name=\"cat[]\" value = $row[1]></td><td>&nbsp;$row[1]</td><td>$row[2].</td></tr>"; echo "<input type = \"hidden\" name = \"id[]\" value = $row[0]>"; } ?> <input type="submit" value="Next"> </form> comp_page4.php snipet <? echo "Hello cat[0] and cat[1] ect...: $cat[0], $cat[1], $cat[2], $cat[3], $cat[4], $cat[5], $cat[6], $cat[7], $cat[8], $cat[9], $cat[10], $cat[11]<br>"; echo "<br>"; echo "Here's id: $id[0], $id[1], $id[2], $id[3], $id[4], $id[5], $id[6], $id[7], $id[8], $id[9], $id[10], $id[11]"; ?> <CODE ENDS>
