I have column -A- that contains different dates formated in the Aug-07 format, column -B- that contains the letters A,D,L ans O, and column -C- that contains dollar values.

I want to add up the dollars values in column -C- but only when -A- equals Oct-07 and -B- equal the letter "A".

I've tried SUMIF but can't seem to get it to work. Any suggestions?

Thank you for your help.
