I have a successful formula in a sheet summary that is as follows
=AVG(COLLECT([Prototype Lead Time (PO DATE and Ship Date)]:[Prototype Lead Time (PO DATE and Ship Date)], [Target Ship Date]:[Target Ship Date], IFERROR(YEAR(@cell), 0) = 2020, [Target Ship Date]:[Target Ship Date], IFERROR(MONTH(@cell), 0) = 1, [New/ Add'l/ Revised]:[New/ Add'l/ Revised], "New"))
When I try and change the column it is looking at at get #Invallid Data Type Error.
=AVG(COLLECT([Prototype Lead Time (Approval to Ship Date)]:[Prototype Lead Time (Approval to Ship Date)], [Target Ship Date]:[Target Ship Date], IFERROR(YEAR(@cell), 0) = 2020, [Target Ship Date]:[Target Ship Date], IFERROR(MONTH(@cell), 0) = 1, [New/ Add'l/ Revised]:[New/ Add'l/ Revised], "New"))
I have checked both formulas and spelling and references and I am not sure what the issue is
Please help
