Not sure how you want them to work but mine turn layers on and off.  here is
a section of my legend template:

[leg_layer_html order=ascending opt_flag=15]
<div>
<input type="checkbox" name="legendlayername[]" value="[leg_layer_name]" [if
name=layer_status oper=eq value=1]CHECKED[/if][if name=layer_status oper=eq
value=2]CHECKED[/if]>
<img src="[leg_icon width=20 height=18]" width="20" height="20">
<a href="#"
onclick="javascript:LegendTemplateLayerInfo('[leg_layer_name]');">[leg_layer_name]</a>
</div>
[/leg_layer_html]

The if block checks on a refresh if a layer is on or not and puts a check in
the box accordingly.  To turn layers on and off you check the boxes you want
then refresh the map.

Hope that helps.

Robin
