I have a simple application (1 table) to track recurring tasks. Each task has a Due-Date, Last-Completed-Date and a Frequency (monthly, quarterly, etc). When a task gets completed, I want to increment the Due-Date based on the Frequency. I know how to create the “logic” for a formula to do this, by creating a formula in the Due-Date Field such as If([Due-Date] < [Last-Completed-Date], AdjustMonth([Due- Date], 1)), however this creates a Formula error – “A formula may not contain a reference to itself directly or indirectly through another formula”. Can someone tell me how to get around this error?
