Well basically 6 Vehicles, they need to maintain 4 bars for oil level in the trucks, everyday the driver gives me a pre trip sheet where they inspect the truck, in that pretrip sheet there is a section where they write in how many bars the oil level is showing, i then take the sheet and need to record oil levels, right now i have a manual hand written system set up, i am very beginner at excel and i want to set up a sheet where i can have the trucks in one coloumn and then a daily log where i type in how many bars are showing so the numerical numbers could be 1-4,the moment i record 2 bars or less for any truck i would like for me to highlight it red, this way it shows me how often im having to fill and what my trend is, PLEASE SOMEONE HELP ME BUILD THIS SHEET, you can help me save my job!
