Excel - Sum column if condition is met by checking other column in same table

Question

I am trying to create spreadsheet to use in a small retail shop.

I have a workbook which contains expenses figures on a sheet and income figure on another sheet.

Answer 1

SUMIF didn't worked for me, had to use SUMIFS.

=SUMIFS(TableAmount,TableMonth,"January")

TableAmount is the table to sum the values, TableMonth the table where we search the condition and January, of course, the condition to meet.

Hope this can help someone!
