I am looking to assign a value to a text string and then insert the
corresponding value into a cell

As follows:

A1 to A100 could equal "NO CHANGE" or "FOR CHANGE"
If A1 = "NO CHANGE" then I1 = "10" else if A1 = "FOR CHANGE" then I1 =
"20"
If A2 = "NO CHANGE" then I2 = "10" else if A2 = "FOR CHANGE" then I2 =
"20"

then this to loop until A100

any help will be gratefully received
