Custom order form created with Databridge not submitting

I have created a custom order form for a page using the form builder in Data Bridge. I have added validation to my fields (this works fine) and then added email functionality (pretty standard).

However, whenever I click the submit button on the form (all fields correctly validated and filled in) nothing happens. It's like there is no action assigned to the form submission (I have double checked the email behaviour and it's set to fire when the current form is submitted and I have also tried changing this to on the button press action).

I don't normally use Form Builder to create forms, I normally hand-code them, but seeing as I have just bought DataBridge I thought I'd give it a go. I've attached my form page file. If anyone can help with this that would be appreciated.
