Hi there, @rr32. I'll share with you an alternative way to enter the opening balance.

The opening balance box is only available if you haven't yet added transactions to the account. You can create a journal entry for the opening balance instead.

Here's how:

1. Go to the Company menu and select Make General Journal Entries.
2. Set the date for the journal entry. It should be the date you pick for the opening balance.
3. On the first line, from the Account drop-down, select the account you're entering the opening balance for.
4. Enter the balance for your real-life accounts for the day you picked. Enter the opening balance in the Debit column.
5. On the next line, select the Account drop-down and then the Opening Balance Equity account.
6. Enter the same opening balance amount in the opposite column as the first line. 
7. When you're done, select Save & Close.
