Thank you for your response.

Yes exactly, the 9B amount on the left side was always prepopulated by my input elsewhere and that gave rise to an error message and we then input the same number on line 9B on the right side and the error message went away.

Now the 9B amount on the left side is not being populated by the program so when you enter the amount on line 9B on the right side there is now an error message because the 9B amount is not being populated by the program and I don't feel comfortable overriding.
