Okay, I have struggled with this for about a month now, and I'm just going to come right out and say that I cannot figure out the accounting worksheet. At all. Someone, pleeeeease help me!

Here's what I have done so far. I have input my sales orders from c-6 (when I started) to c-9. I have created 4 accounts for myself: Personal, Business Tools, Inventory - Gifts to customers, Inventory- gift baskets.
In A. Sales to customers, do I put ONLY customer Sales, or would I include amounts from my four accounts above? If I do, should I put them at my cost, or at retail and then indicate my cost using the discount fields? Can someone explain why I should NOT put any of my purchase information in A?
Thank you so much for your help! My brain just keeps going round in circles!!
