It showed 2 parenthesis were missing. I attempted to add them to the end, however I got an error that the syntax was incorrect. Screenshot of the error shown at the bottom.
I am having issues with this formula. It is showing EVERYTHING as overdue (previous version). It is possible that the "Actual Implementation Complete Date" column could be before OR after the Target Implementation Date (which is a formula). Either way everything should not display as Overdue.
=IF(AND(status@row = "Complete", [Actual Implementation Complete Date]@row <= [Target Implementation Complete Date]@row), "No Escalation", IF(AND(status@row = "Complete", [Actual Implementation Complete Date]@row >= [Target Implementation Complete Date]@row), "Over Due", IF(AND(status@row = "Open", [Actual Implementation Complete Date]@row >= sum([Target Implementation Complete Date]@row - 14), [Actual Implementation Complete Date]@row <= [Target Implementation Complete Date]@row), "At Risk","-")))
