Customers can’t select my variations

[CatsnHatsCrafts]

I just made my first listings and I had two friends try and purchase my item. They both said it wasn’t allowing them to select a color variation no matter what they clicked. I am unsure of how to fix it

[UniqueGiftOrnaments]

I tried and was able to select the color.

[bluegreenjewels]

I was also able to click on the variations.  (cute cat hats, btw!)
