Good afternoon StormcrowHammerhand and thank you for posting on the Final Fantasy XIV Technical Support Forums.

Are you referring to the reward screen at the end of a quest? If so, the quest will give you one of the rewards (but not all of them). It requires that you make a choice first, then the 'complete' button should work.

If you are referring to something else, please elaborate. You can upload the image to another website and link it here if that is easier.

We hope we can be of assistance in helping you enjoy the exciting world of Final Fantasy XIV!
