Looking at the chart below, is there a way to limit what is entered in the
"Actual" column

E.g. in cell B2 10% has been entered
in cell B3 I want to limit it so the max you can enter is 90%
in cell B4 I want to limit it so the max you can enter is 80%
And so on

Target Actual
10% 10%
20% 10%
30%
40%
50%
60%
70%
80%
90%
100%


Thanking you in advance
Derek
