Coupon entry not visible on front end

I have created a coupon for use, and I dont see it on the registration form front end.  I cant see any way to show it, its enabled on the configruation page, and Ive selected the event for it to be used in, as well as not setting a coupon use limit for testing purposes

Hello Craig

Could you please send me screenshot of the coupon setting? Maybe there are something wrong with the coupon setting and it is not available for that event
