Dear Rajiv..that is how one should learn....take the BABY steps.... Experts are here to guide..... You have the running balance code/tdl.... find the field which refers to the value.... in that field you add the line........Color : If $IsDeemedPositive Then Blue Else Red Do not be afraid of experimenting...........
