I am trying to make a small database in MS Access for a Gas Station, where I need to store data for every Single Fuel Dispenser's Current and Previous Readings. Which will then subtract Previous Reading from Current Reading and Calculate the Sales on a Given Rate. There are 4 Fuel Dispensers Installed on the Gas Station and every dispenser has 2 nozzles. I have Created 1 table for each Nozzle. Now I have a total of 8 tables with these fields (ID, Date, Rate, Current Reading, Previous Reading, Total Sale, Credit Sale, Cash Sale, Total Amount, Discount and Description).
I also want to make Forms so that the User can enter the data from the Forms for each Nozzle. Can someone please help me with this? I have been trying it for the last four days and I am still stuck and cannot go further.
NOTE: For each nozzle the readings will be Different.
