<p>I have a checkbox in AddForm and EditForm that needs to update a hidden TextField onClientClick. I wrote it in plain html and javascript first outside of XMod Pro and it works fine. When I add it to my form, the function isn't even called, so obviously there's a js error somewhere.&nbsp;</p><table><tbody><tr><td><a href="http://dnndev.com/fiddle/fid/552">http://dnndev.com/fiddle/fid/552</a></td></tr></tbody></table>
