Refreshing a parent page from a child popup

[evanburen]

This code from my child popup page refreshes the parent page which
works well but I would really like to refresh just frm1 on the parent
page instead of the whole page. Is this possible? Thanks.

child page:

<img border="0" src="close-panel.jpg" width="113" height="21"
onclick="opener.window.location.reload();self.close();return false;">

parent page:

<form name="frm1">
<SELECT onChange="ordering(this.options[this.selectedIndex].value);">
<option alue="Div16">Div16</option>
<option alue="Div17">Div17</option>
</SELECT>
</form>
