The website is not validating because of an error that comes in after the form tag - in the div under the class "label".
Validation error: "Attribute name not allowed on element div at this point"
This is the portion highlighted
<div class="option hiddend" ); ?>">
The topic is covered here at Stackoverflow:
Found the relevant css -- shouldn't be a "name" class, but an "id" ?
Not sure which file I need to revise in the php or js to fix this... any help would be appreciated.
