problem with Configuring a Coupon

I am usung Coupon for VM Pro and want to configure Coupons to mail the Coupon Code to purchaser. The Coupon Code is supplied from other party.

The instruction for configuring shows different fields so I am really confused:

Example 1
Coupon Code: 1234567890123456 (16 digits)
Published
Function Type: Product (Coupon not available)
Number of uses: Total #1
Discount Type: Overall
Value: 10.00
Minimum Value:0.01
Expiration Date: blank
Products: blank.
Customer: none chosen
Products: none chosen

but I find different fields when trying to Configure:new Coupon

Function-Type: Coupon
Function-Type2: Product
Coupon Code: 1234567890123456 (16 digits)
Published
Percent or Total: Total
Value: 10.00
Number of uses: Total #1
Minimum Value: 0.01
Expiration: blank
Customer: none chosen
Products: none chosen

Installation check = OK
what did I wrong?

please help!

AwoCoupon pro is a backend function and does not have the ability to emails coupons for order placed, unless it is a gift certificate. Is that what you are referring to? If so, take a look at this blog on how to set it up:
