Where does the coupon code get entered on Dollar rental car site?

I have been going round and round on this site! I have three codes I want to try, and the only spot I can find to enter a code is on the first page where it says "Corporate #. But when I enter the codes I have (KISS2, 918, OCVB), I get an error message on the next page. So where do you enter these codes??

Go to the "specials" tab and you can reserve a vehicle using codes there under "promo code".
