Can I do it? If yes, can somone plase tall me how?

Thank you

One way to do it is to use Crystal's Highlighting Expert like this...
Open your report in Crystal, right-click on the field whose background you want to change and select Highlighting Expert from the context menu. This lets you add multiple conditions to a cell, eg if a cell's contents is > 250 then make the font Bold & Red etc. You can add borders, change font style & background etc.
