I must be doing something wrong but I cannot see what the problem is. I have a sheet where I want to colour code cells depending on their values. In my case it is cells F3:H150 and L3:O150. The values are all percentages. I have a single conditional formatting rule applied to all these cells. It is a 3-Colour Scale with the types set to percent for minimum, midpoint and maximum. The colours are green for 0 orange for 50% and red for 100%. I am sure you will agree this is pretty straight forward.
However, it is behaving very strangely. Sometimes in some cells it works but in others it shows the wrong colours. For example in some cells it will show low values as green (which is correct) but in others low values are red. What is even worse. If I change a cell's value other cells which are totally unrelated change to random and wrong colours as well although this doesn't happen with every cell - just some.
I have used this before with other spreadsheets and it worked fine. Not only that but in the same spreadsheet but in another sheet it also works fine. As I type this I am wondering if there is some corruption in my spreadsheet. Could that be the problem?
Any suggestions will be gratefully received.
Best wishes.....
