Please Help! Netscape is not behaving with my javascript!

Hi,

I have a javascript calculate subtotal function on my page to add up what customers
have selected to purchase. It calculates fine with Internet Explorer. With Netscape, all of the items that are over $1.00 claculate fine, but any items that are under $1.00 calculate showing two different decimal points (not places, but points). For example, for 50 cents, I've tried using $0.50, $.50 and even $00.50. and not any of them calculate correctly.

If you would like to look at the code, here is a link to the page
"http://www.dragonherbarium.com/test/test.html". Is there a way to code it so that
both browsers will work?

Any assistance would be greatly appreciated.

Thank you,
Judy

Got it fixed!
Thanks
