Live form has bugs that the preview version does not.

Preview works fine: http://www.jotform.com//?formID=52320011039841

Embedded live on http://www.kidsunlimited.com.au/pay.html

Not displaying data under Kids Unlimited Enrolment page break when Selecting the 2nd or 3rd ratio button options.

Also on Page 2, when selected payment via Direct Debit isn't displaying the payment form.

Kindly update your iframe src value to point to your form link i.e http://www.jotform.co/form/52320011039841

<iframe frameborder="0" scrolling="no" style="width: 100%; border: medium none; height: 434px;" id="52320011039841" name="52320011039841" allowtransparency="true" src="http://www.jotform.co/form/52320011039841" onDISABLEDload="window.parent.scrollTo(0,0)"></iframe>

Also increase you form height to cater for the added fields to prevent them from being cut off, please let us know if you will need additional assistance or clarification
