Trying to make a "Daily Log Sheet", that calculates number and hours for activity

OK, I have a new problem, The Daily Log is working great (blank version attached), but now my supervision also wants to be able to have us turn in a weekly stat sheet... in addition to the quarterly and yearly sheets.

I've added a "Weekly Log Generator" tab... which I was hoping I could do some magic with as follows:

The user would enter in the beginning and ending date of the particular work week they want to generate a report for... and then the stat sheet would be filled out appropriately on that tab, so they could print it out.

Given my current caveman spreadsheet setup, any ideas on how to accomplish that without starting from scratch? I'm sure I should have gone with the data table suggestion early on!

Thanks for any help!
