I have two rows of three items in my "earrings" category, and as far as I can tell each product has the same settings.
The upper three products have View Details buttons, but curiously, the lower three products have lost their View Details button, and instead each has "Add to Cart". Can anyone help?

It's because you have another option to choose from besides amount. Can't add an item to a cart when you don't know what color they want.

Thanks, I see that now. I swapped them around and re-uploaded, yes that's the way it goes.
