Thanks but I might not be entering the time into the field "now", it might be after the fact.
I monitor bookings and use for 17 local sports fields to plan maintenance schedules but to date have only done so using paper and pencil. I have minimal experience with Excel and hope that there might be a relatively easy spreadsheet solution to my situation.
I need to monitor bookings as well as use because not everything booked results in a field being used (for various reasons) which affects my maintenance scheduling.
What I visualize being able to do is enter bookings as they are made then follow up later confirming that the booked time was either used or not. I then wish to be able to look up at any given point, the total hours used for any field (to determine maintenance requirements) and compare that figure to the total hours booked for that field (to monitor reasons for non use).
I would welcome any suggestions as to where I might start.
