help with quiz code please

If i get rid of the value drop down boxes and replace them with radiogroup1 boxes (numberes 0-5 values 1-5) renaming them first , when i click results nothing happens.

please use the code above it works save it as any html file you want.
so if i remove this (drop down)
<SELECT NAME=”first”>
<OPTION VALUE=1>Yes
<OPTION VALUE=0>No
</SELECT>

and replace it with

<label>
<input type=”radio” name=”RadioGroup1″ value=”1″>
yes</label>
<br>
<label>
<input type=”radio” name=”RadioGroup1″ value=”0″>
no</label>

when i hit get results …..nothing….

maybe something to do with

function AddItUp(form) {
var item, firstValue, secondValue, thirdValue, fourthValue, fifthValue, sixthValue, seventhValue, eighthValue,
ninthValue

// Get the value of the item that’s selected in the first list
item = form.first.selectedIndex;
firstValue = eval(form.first.options[item].value)

Also in #JavaScript _↴
