I am trying to record a bill and keep getting a message that says:

"QuickBooks has detected that you have no items or that one or more of your amounts is not associated with an item. Fill in an item or go to the Item list to make sure all items are associated with accounts."

What does this mean?I have checked and every item on the bill appears in my item list. if there is a problem with an item why doesn't it tell me which one?
