Sumifs / index / match in another sheet

Hello all,

I need a little help with a Sumifs + Index + Match formula, in order to do this:
- look for "ABCDEFGH" (Sheet2!A7) and "WEEK 37 2019" (SHEET2!G3) in sheet1 and make sum between the values in Sheet1 column F - for week 37. (see attachment)

If you have any free time in order to help, would be great.
Thank you in advance.
