Column I in my excel file shows unpaid invoices. Column K shows uninvoiced items. Column P shows the customer's balance on account . Most of the time, P should be greater than I+K. However we want to be able to easily spot the customer files that are close to or have exceeded the customer's balance on account. The third party program we use to generate the excel table does not give us the opportunity to filter before downloading, so I need to come up with a way to get Excel to only display lines where I+K is greater than OR equal to OR (a percentage) close to being equal to P. Any ideas?
