Adding Hours Worked minus lunch break IF over 5 hours

I'm attempting to make a simple time sheet for a handful of employees. I'd like to enter the clock in time and clock out time for each day. The end cell should be the running total for the week. The tricky part for me is having the formula subtract an hour for each day that is over 5 hours.

I've attached an example spreadsheet

Thanks for taking a look!

I had to add *24 after each parentheses but that ol' ugly thing worked... lol

Thanks for the help!!!
