How to add Excel cells by month?

Question

excel

Hello.
I have 2 excel spreadsheets.
1 table of columns: Date, Name, Amount
2 table of columns: Month, Total amount
How can I correctly write the formula in the "Total amount" cell so that it automatically sums all the values ​​from the first table for the month indicated in the 1st column?
*I would like that in the 2nd table, the cells in the 1st row could be selected and multiplied in height, so that the formula would automatically adjust to all future months in order.
Help me please :(

Now there is no access to Excel - dig towards the SUMIF function.
