I'll relay your thank-you message to Lurleen, WinnLawPC. I'd like to shed light on this.

I think the description in the register your mean is the Memo field of each transaction. By the way, that's the memo of the entire transaction, and yes, it's the same memo you see on the Expense Transaction page. However, anything you put in there will not reflect into the Description of the line items if this is your goal. If you can notice on an expense transaction, the Memo field is separate from the item descriptions.

The screenshots below show the memo of an expense transaction on different pages. 

Feel free to go back to this thread if you need more assistance in updating your transaction descriptions or memos.
