Help Me Please

I feel as if I am a woman of normal intelligence but for the life of me I cannot figure out what I am to do on this puzzle. It says I need 2 Supercombos, "Make a combo of 3 or more superstocks ending with a middle column. I cannot for love or money figure out what I am to do. Please you with a mensa membership help me. Thank you so very much.

I thank you, my husband thanks you and my computer that was really taking verbal abuse thanks you. Sure is funny how that sailor language just pops out of your mouth when you get frustrated and I wasn't even a sailor.

Your help is greatly appreciated and is everyone at BFG. Hands down all of you are the greatest!!!!!!!
