I'm trying to improve the log that I use to track my workers whereabouts so I can improve job costing. I've been manually adding up different jobs from the attached sheet but want to make it do this automatically. I've got a column with hours worked on a job, then a column with the specific number on for that job, and then a column with the job's name. I want to find out how to make something at the bottom of the sheet that will take column E and add up all values in column F that correspond with that certain value in E. Please see attached sheet, I can write better instruction on there. Thank you.
