Gelato Mio - UK based retail company is trying to upgrade its cashing up form. Currently we are using the enclosed spreadsheet. Store manager fills the blue fields at the end of the day and the forms automatically calculates any discrepancies between the actual versus theoretical figures. I am looking to develop a zoho form with the same functions: namely it should not only record data, but also give immediate feedback to the manager about money in surplus or missing, so in case there is any issue, they will be able to double check for possible errors. In the enclosed sheet blue cells are input cells and orange cells are output cells
