Need help in creating Color Combination logic for Matrix report

Hi Shrek,

Logic for Color coding is the combination of probability and impac value.

Logic is like If Probability is Low and impact is unlikely then color=Red

                  If Probability is Medium and impact is unlikely then color=Blue

                   If Probability is High and impact is unlikely then color=green

similarly    if probability is Low and impact is Likely then color=dak blue

but when I create expression based on this logic, only those text box gets colored which are having Risk Id value, remaining text box don't get colored.

Thanks
