You can't record the journal entry; a message says the transaction is unbalanced
Before you can record a journal entry, the amounts that appear in the Debits and Credits must be fully allocated. That is, the Total amounts beneath these columns must be the same and the Out of Balance amounts must be blank.
When the journal entry is fully allocated, the Out of Balance amount near the bottom of the window will be blank, and you'll be able to record the transaction.
