Javascript in IE7

I am having a problem with some javascript. It seems to work on Chrome and IE9 but not in IE7. There are several radio options in the code below, one selects the product type (Battery, rechargeable or wired) and another selects the payment option (1 or 3 year package). The selections of these two controls should then set the price, but IE7 gets the result wrong in every case. It even gets a different answer for the same selections depending what happened before.

Clicking the sub, vat or total boxes, the values change to the correct value. Any ideas please?
