Hopefully someone can stay with me on this. I have colums A-H and 8 rows.

In colum C is the start time of my shift ex) 9am; in column D I have my
lunch out time ex)12 pm. In column E I have my lunch in time Ex) 12:30 and
in column F I have my Finish time ex) 5:30

What I want is in column G is the total number of hrs for that day and I do
not know the formula for this.

So it's 9 am start, 1/2 hr for lunch and quit at 5:30 equals a total time of
XXXX which should be column G

Hope someone can help
thank you
