how to sum formula to get total value from another column times with another column

[leakhna]

Hi,

I think there should be way to get total value from sum of each row into just one column.

just like sumif without critical range ( i only want to sum row A with many items x with row B that contain value of each item).

I might not have clear explanation here but the excel sheet may address you all on what i want.

Please help to review and share with me.

Thanks,
Leakhna
