Hi,
I dont know if it is related, but i find when something is not referenced correctly, the form stops processing.
When i clicked a radio button in table 2 or 3, the javascript console threw an error. Not on just one radio button, but many. Invoke the debugger with CTRL+J when you preview the form.

I find it hard to look at an unfamiliar form but I looked through the code for the checkbox - form1.Page2.Table3Sec1.Row2.cb16::change - (JavaScript, client)
I searched for Row14 in the code and it references: Page2.Table3Sec1.Row14.cb33.rawValue == "1"
Unless i am missing it in my quick look at the file. That table does not appear to have a Row14.

I dont know if that is causing an issue. The No radio button code seemed fine to me.
