HELP PLEASE! Dropdown menus

So my first question is that I have been making a dynamic product page for my wixstores.

I am trying to add a drop down menu so that my customers can choose size, color, etc. When I try to connect the data set from my product options of wixstores to my dropdown menu. It just won’t be an option I can choose.

Am I missing something? I really just want to connect my dropdown menu to my product options. Please help! ive been wrapping my brain around this for far too long.

Much appreciated!
