I want to sum a column of an Expenses table where the description matches the description on the row of my Rates table.
After reading the method description I had to make many inferences.
Filters the list for values that satisfy the condition and then calculates the sum of those values. If no sum range is specified, all values in the range will be summed.
=SUMIF( table_variable_name.column_variable_name, ">5", [table_variable_name.column2_variable_name])
It was not clear if the quotes are always needed around the condition or only if using static values.
When it says a sum range, it makes me think of a max row count but the example shows just a variable in there, which then makes me think that is where I put the field I want to sum. Yet the language doesn't add up (no pun).
So here is what I wrote, which does not throw any errors, but the value is always zero.
=SUMIF(Expenses.Description,"=INDEX(Rates.Description,ROW())",[Expenses.Amount])
