Hi mett,
A few things to look at here.
First this is an incredibly long form to debug. Please try testing on a short version. Here's the cut down version that I've used.
<table width="100%" border="0" cellspacing="2" cellpadding="2">

There's an example of everything important but much less room for errors and confusion.
2: You have <form> tags in your code, ChronoForms adds it own form tags and having two sets leads to problems.
3: You have a default select option
<option value="sel" selected>-selectati-</option>
and the validator can't tell the difference between this and the 'real' options.
4: Validating radio buttons takes a slightly different approach. Her are the notes from Andrew Tetlaw's
documentation.
*To use the validate-one-required validator you must first add the class name to only one checkbox/radio button in the group (last one is probably best) and then place all the input elements within a parent element, for example a div element. That way the library can find all the checkboxes/radio buttons to check and place the validation advice element at the bottom of the parent element to make it appear after the group of checkboxes/radio buttons.
It doesn't look as though ChronoForms implements this quite as well as it should.
I'm not sure that these fixes will sort out all your problems but please try them and see what is then working - or not.
