Hi John,
The postback is through ASP Webforms. Visual Basic, it's an old legacy system I am trying to style up a bit nicer for portable devices.
So on button press it processes the checkbox/select/radio button value and adds a price to the product.
Theres not much code apart from including jQuery, then jQuery mobile in the head tag and the inputs are normal html inputs with no data tags on them.
I can try and put some code together if possible but probably will not replicate the issue with the webforms postback.
Thanks.
