Hello people

ok...im not sure if what im asking is actually possible but i'll ask anyway.

i have a form which adds records to a table

below the form i have some script which shows all the information that is in the table

<tr>

<td width="54" align="center">Model </td>

<td width="48">Serial</td>

<td width="89">Issue Date</td>

<td width="52">Issuer</td>

<td width="65">Division</td>

<td width="89">Comments</td>

</tr>

<? while ( $myrowRes = mysql_fetch_array($resultName) ) { ?>

<tr>

</tr>

<? }

what i would like to add is in the form, 4 or 5 check boxes which, if selected, in the dispay of the mysql table has a lilttle tick image.

any ideas if this is possible??

Theres a base. Change "field" and tweak it as needed.
