Hello,
In the sheet summary field (property is Text/Number) I am trying to sum invoice amounts (Column is called Amount) that are submitted each month (Column is called Invoice Date and is a Date column) using this formula but getting Invalid Data Type:
=SUMIF([Invoice Date]1:[Invoice Date]22, MONTH(@cell) = 4, [Amount]1:[Amount]22)
4 = April
What is also strange is the formula will somehow change to this:
=SUMIF([Invoice Date]1:[Invoice Date]22, MONTH(@cell) = 4, Amount1:Amount22)
Any help is much appreciated.
