modDiscounts.asp help needed

Unfortunately it is in the modDiscounts.asp.  I just deleted the coupon and created a new one.  It saves it without error when I select Discount Amount and select zero amount.  It shows no radio button selection when I click on it to edit it.  It does save the radio button when I do put an amount in.  The page checks for zero amounts, but I cannot read the code well enough to change it.  My ASP skills are none existing.

I'm pretty sure the problem is on the modDiscounts.asp page, since it does not even save the radio button dollar discount with the 0.00 amount.  It will only work if I put in 0.01.  It does not save zero amount.

I'm still on 3.51 without the one page checkout.  

It's still not working.  I can create the coupon and do not get an error message.  I've noticed that the radio button is not selected when I click again on edit this coupon.  It just doesn't work when I place an order.  I called it "Free calendar", select fixed rate of $0.00, and selected it to be automatically applied to all orders, and available for retail and wholesale customers.  It basically does not show in the check out, even after selecting a shipping option.  It will show, if I put a value of $0.01 in.  I think there is somewhere a checking mechanism.  

Thanks, looking at it now. What error message does it give you when you try to save a discount with a $0 value? Did you make sure to check "price discount" even though you are entering zero? I know if i try to save a coupon without selecting either price or percentage that it doesn't work.

Like I said earlier, It works fine on my site and I can't find any code on this page that looks like it would restrict it. Going to keep looking.
