Drop Drown Calculating Totals

Hello. I have a sheet with three columns. Column A is a list of levels (e.g. 1, 2, 3, etc.). Column B shows one value for the levels and Column C shows a second value for the levels:

Lvl	Val 1	Val 2
		
2	9	168
3	10	174
4	10	183
5	11	190
6	11	199
7	12	205

The values are cumulative so that, increasing from level 2 to 4, the total of value 1 would be 29 and the total of value 2 would be 525.

I'd like to have a drop down showing the starting level and another drop down showing the ending level so that, after selecting them, the total of value 1 would be displayed in one cell and the total of value 2 would be displayed in another cell:

Beg Lvl     End Lvl     V1     V2
    2            4         29     525

Is this something that can be easily done?

Thank you for any assistance!

Please see attached.

In the future please attach a sample workbook so we don't need to create one from scratch. Thanks,
