Adding up value based on another column

Alright, so I have a column with names and a column with amounts. I need to add up the amounts for each name. The names have first and last in one column.

So names are in column A amounts are in Column G And I need to total all of column G for each column A.

The names change and I’ve got hundreds of names. Ideally I could have this on a separate sheet?

I just need to pull the name, and the total for each name.

I’m at a loss for how to do it without manually entering the name which would be very time consuming.

I hope I explained this correctly
