I need a very basic tool to calculate available appointments for my installation business. Please see the attached spreadsheet to get an idea of what I have been using. I will need an admin side to be able to add and display for different cities. The attached spreadsheet is only for Dallas, but I need to be able to have the user switch cities and see the appropriate data for that city. Once the user books an appointment, it needs to subtract from available appointment. please review the spreadsheet and ask me any questions via PMB. You MUST be able to work on this NOW, and complete in 24hours.
