Report & Summarize Counts

Refer to the attached sample workbook. I need to track daily tasks of our staff and then indicate these tasks on the "Activity Report" sheet.

Each task will have a code and I will indicate; by menas of the code, which activity was done by inserting that code in the time slot provided.

Once each day is completed; I need to tally up the amount of each activity that took place and it will be diplayed in the "Specific Activity Summary" section of the sheet.

Also; once the tally for each activity is completed, the amount of time spent on that activity will be indicated on the "Daily Activities Summary" sheet.

How do I go about linking the specific cells to be able to create this "tally" and "summary."
