I am trying to create a sumifs function that sums up all of the expenses in a second sheet if they are not labeled "travel". I attempted it with an all-inclusive OR function and then tried it with the NOT function and neither seem to work. It seems that they need to look at cells specifically within the sheet and can't look back at the cross referenced sheet. What am I missing from the use of NOT or OR, or some other formula component?
Here is what I have.
=SUMIFS({CashExpenses}, {CashExpensesMonth}, [Month or Quarter]@row, {CashExpensesCode}, [Code]@row, {CashExpensesCategory}, NOT("Travel"))
