I flipped through your code, compared to mine, this should fix the problem:

/*
	Get product option value -modified
*/
function getPOValue(c) {	
	if (document.getElementsByName('product_options['+c+']')) {
		var radios = document.getElementsByName('product_options['+c+']');
		for (var i = 0; i < radios.length; i++) {
			if (radios[i].checked) {
				return radios[i].value;
			}
		}
	}
}

I fixed the original post #18 to show this code. All that is changed is:

'po'+c is now 'product_options['+c+']'

My apologies. That is my fault. I didn't check the code that I posted.
