Situation: A worksheet whe
-there are many duplicate ID numbers in Column A
-there are unique values in Column B

What I'd like to do:
Obtain a sum of Column B values for each distinct ID number, so that I'd get
the following results: 1111=$5.6, 2222=$4.5, 3333-$4.3, from the data below:
Col A Col B
1111 $5.0
1111 $0.6
2222 $3.5
2222 $1.0
3333 $4.3

Any assistance will be greatly appreciated. I've been searching the help
files, but I don't think I'm using the right lingo!
