Thanks to all who posted back.
I decided to go with the following code:
[leg_group_html]
<tr>
<td align="left" valign="top" colspan="2"
bgcolor="#FFFFFF" nowrap>
<font face="Verdana, Arial, Helvetica" size="-1"
color="#000000">
<input type="checkbox" name="layer_status[]"
value="[leg_group_name]" [if
name=layer_status oper=eq value=1]CHECKED[/if] [if
name=layer_status oper=eq value=2]CHECKED[/if]>
<b>[leg_group_name]</b>
</font>
</td>
</tr>
[/leg_group_html]
[leg_layer_html order_metadata=WMS_ORDER opt_flag=15]
[/leg_layer_html]
[leg_class_html order_metadata=WMS_ORDER opt_flag=15]
<tr>
<td width="6" bgcolor="#FFFFFF"> </td>
<td align="left" valign="top" bgcolor="#FFFFFF"
nowrap>
<font face="Verdana, Arial, Helvetica" size="-1">
<img src="[leg_icon width=18 height=12]"
width="18" height="12" border="0"
align="left"> [leg_class_name]
</font>
</td>
</tr>
[/leg_class_html]
- thanks again -
