Can't figure this one out.
Problem: I set up my option name: Size. Then I set up my option values: Small, Medium, Large, X-Large, etc.
I went in to Attributes Controller and selected Category > Product, then clicked "Display". I proceeded to add my desired attribute name + value and hit "Insert". I only needed one attribute value for this product (Medium). Everything looked good to me. I then do a test purchase of that item on my site by selecting the "Medium" attribute that appeared for that product...suddenly a yellow error box appears above saying, "Please correct the following: On the Option for: Size You picked an Invalid Selection: Medium"
What did I miss?
