I'm using an excel spreadsheet that tracks lessons along with who completes the work and how long it takes. I'm looking for a formula that can sum the time they work based on when their name is selected from a dropdown list. I also need it to take that total and calculate out as to 25% of the total project for that person. I'm trying to track each person productivity on a large project.

I can provide my spreadsheet if you like. Just let me know.
