Hi phantastes, Thanks a lot for ur reply. I was also thinking in the same lines. But i didn't know how to implement it. Can i have the values in the variable as comma separated strings such as :- '1000','1001','1002' Also can you kindly explain me the variable expression code :- "".equalsIgnoreCase($V{City_List}) ? $F{city} == null ? $V{City_List}:$V{City_List}+""+$F{city}.trim(): $F{city} == null ? $V{City_List}:$V{City_List}.contains($F{city}.trim()) ? $V{City_List} : $V{City_List}+", "+$F{city}.trim() A brief walkthrough will help me understand. Thanks a lot in anticipation Samrat.
