Firstly, cant figure out why it requests me to put an input in when its directly linked to the combo boxes on the main menu. But the second thing I need to figure out is how to sum the acres for my tons/acre just once for each field, because a field might have 3 inputs but doesnt mean you should count the acres 3 times. You all have always been helpful in learning how to properly format these things, as well as showing how to fix my issues, so I'm looking forward to any input on either issue, as well as the database as a whole.Sales Test.zip
