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.
We can say that the common ground between the both sheets are the month.
I would like to write a function, which will only select those expenses of a specified month.
Something like -
=SUM(IF( Table4[Month]="January", Table4[Amount]))
// I want the sum of all expenses of a given table for only
// those months which are january etc.
I tried using the above, but it failed.
This should work, but there is a little trick. After you enter the formula, you need to hold down Ctrl+Shift while you press Enter. When you do, you'll see that the formula bar has curly-braces around your formula. This is called an array formula.
For example, if the Months are in cells A2:A100 and the amounts are in cells B2:B100, your formula would look like {=SUM(If(A2:A100="January",B2:B100))}. You don't actually type the curly-braces though.
You could also do something like =SUM((A2:A100="January")*B2:B100). You'd still need to use the trick to get it to work correctly.
Actually a more refined solution is use the build-in function sumif, this function does exactly what you need, will only sum those expenses of a specified month.
example
=SUMIF(A2:A100,"=January",B2:B100)
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!
