The "Data" tab in my spreadsheet contains a list of dates in column J (format is date, example: 1/27/2012).
On the "Monthly Hours" tab column A contains each month, column B contains the workable hours in that month.
........A........B
1....Jan......176
2....Feb......168
3....Mar......176
4....Apr......178
5....May......184
etc.
I need to look at column J in the "Data" tab and for each different month in that column, I need to find the value in "Monthly Hours" column B that is associated with that month. Each of these values must be added together. (each month counted only once regardless of how many times it shows up in column.)
The goal being that the formula calculates the total working hours for the months listed in column J on the data tab.
