function petreference_optionwidgets_validate in Previewable email templates 6

Validate a select/buttons element.

Remove the wrapper layer and set the right element's value. We don't know exactly where this element is, so we drill down through the element until we get to our key.

We use $form_state['values'] instead of $element['#value'] to be sure we have the most accurate value when other modules like optionwidgets are using #element_validate to alter the value.
