In using xlookup function, the formula looks up the current month (formula in cell: =text(eomonth(today(),-2)+1,"mmmm") to look up in a row of months: Oct, Nov, Dec,....September, and return the corresponding total commissions for the month. The results appear correctly, with the exception of November (col. D) and July, (Col L). For those two months, it returns #N/A. I don't know why this is happening. I have checked the months have the "mmmm" custom format. Can you help?
My formula is: xlookup(C29,C2:N2,C28:N28)
xlookup(month, range of months, range of commissions).
Please check your data in C2:N2. That could be extra space like "November " or something similar. If month names are entered manually, type January in C2 and drag it till N2, all names will be added correctly.
