I'm setting up my first AbanteCart. I added options for t-shirts: Size, color, shirt type, and image location. Now I want to add values for these options. In the documentation it says: "After creating the new Option please select it's name in the Options list and insert new option 'values' by click on {+} button", but I can't find an "Options List" where I can insert values by clicking on a "+" button. Where is this "Options List"?
