I need to look up names from column 1 then sum numbers from column 2. Some names in column one appear more then once. (The spread sheet I am working on has 7400 rows!!!)

Example:

```
Column A ColumnB
Nad 10
Baz 15
Nad 50
Nad 5
Baz 45
Baz 10
Ash 15
Ash 25
```

How many total numbers for each name. So for Nad it should say: 65
