No worries
@HoosierHarvester! It took awhile for people in the Beta swap (me included) to figure this out. Once you add an item to the swap (make it public and ready for swapping) you then need to go back in your swap list and click on the little check mark by the name of the seed you listed. It should turn green. Only items with the green check are considered available to be swapped.
