OC Quantity Break Order Limits

Ryan assisted me in getting my most challenging product into my shopify store. My issue was that I am selling Pin Buttons in Assorted Sizes. So basically I have 3 different size buttons but customer can mix sizes and quantities if they get a minimum of 100. Goal was reached and I am quite satisfied. I've been putting this off since I had a few false starts trying to do this. However, someone I know wants to place an order so I had to get this done tonight.
