Hi! Question.. I have got store list on B3:B7, dates when the vehicle changes for the store on D3:D7, vehicle registrations drop down list on F3:F7 and when the next change is due required on H3:H7.. now what I want to do is if the same vehicle is used for the same store 4 days in a row to be highlighted red in the next change due row and no change at all if no vehichle is selected. I can't work it out how to do that as I'm pretty new at doing all that on excel. Thanks in advance!
