- I try to take the value of three ratio by the command document.form.q_0_1.value (exampe for the first ratio, and they are put in the form named 'form'. But i cannot, can anyone tell my why ???

I don't fully understand the question, but I can tell you that if you want the value of q_0_1, since there are more than one, you would need to do something like so:

for (var e=document.forms['form'].elements, i = e.length-1; i >-1 ; --i)
if(e[i].name=='q_0_1'&&e[i].checked)
alert(e[i].value)

to get it.
