Please help! Why won't my image pull from "Variant Image" for E-Commerce?

This is something that should be so simple but I am struggling.

I am trying to pull the variant image for the different colors of the headboards we are selling, but “Variant Image” won’t appear on the drop down:

When a customer selects a color, I would like the photo of that color to appear so they know what color they will be getting. Why won’t variant image appear?
