I'm trying to create a method of tracking the use of hours across my business over and above standard hours. There are three data fields; over hours, overtime and agency. I've created a dropdown menu which gives those three options but what I'd like to happen is that when they select Agency (for example) I'd like the cell to go empty and allow them to enter a numerical value, let's say 10 for Mon on HCF. Additionally, as it's agency I'd like the figure 10 to run red and automatically populate M11 in the same colour. Totals I can sum easily enough. Thanks!
