Error when importing

I'm trying to import 1000 gift certificate codes.
I have a csv file with ID, Published, Coupon Code, Funtion Type, Percent or Amount and Value columns in it.

When uploading it gives me an error:

ID: 1;"KR0385540";"Published";"Gift Certificate";;"Percent";;100
-- That coupon code already exists. Please try again
-- Not enough columns to process

for all 1000 codes. What am I missing.
If possible reply ASAP as I need it working by tomorrow evening.

Thanks.

Hello,

The easiest way to get an import template is to create a coupon, in your case a gift certificate. Then go to awocoupon->reports->coupon list and run reports. Then export it to excel. You now have an import template. If you change the coupon code to something unique, you can then import it.
