Can anyone suggest what is wrong with my formula? I get an #INVALID OPERATION result. I've looked at it for too long and can't find the issue. Thanks.
=IF(NOT(ISBLANK([Order Date]1)), "Ordered", IF([READY TO ORDER]1 = 1, "Ready to Order", IF([CPM Complete]1 = 1, "CPM Need Approval", IF(NOT(ISBLANK([Vendor Quote requested (Date)]1)), "Vendor Quote Requested", IF(AND(NOT(ISBLANK([Aaron O'brien approval]1)), NOT(ISBLANK([Jimmy Yang approval]1)), [James Keng approval]1 = "Approved"), "PIF Approved", IF(AND([Market Study Complete]1 = 1, ISBLANK([Aaron O'brien approval]1)), "PiF Needs Approval", IF(AND([PM Recv'd Request]1 = 1, [Market Study Complete]1 = 0), "Mkt Study & Sourcing ", IF([PM Recv'd Request]1 = 0, "New Project"))))))))
