Mutiple Coupons

I would like the customer to be able to use mutiple coupons. I have the box selected in the awo coupon configuration... but when I go to check out and add one coupon the coupon box goes away.

Is there something I need to adjust so that the coupon box remains after adding one coupon code?

How can a customer add two coupon codes. There is one for a 5% discount on certain product and one for a 15% on another product.

Thank You for your support. This is excellent software by the way, there is nothing out there like it for Virtuemart, so thank you!

Due to the way Virtuemart renders coupons, the customer would have to enter all the coupons at the same time, separated by a semi colon. So for example, if the customer has coupons a12w and r3c, this is what would would be entered in the coupon code field:
