Thank you, Paul. Yes, receipt number is numeric. Should I then insert 0 into all places where receipt number is present as well as not present? i.e

{IF«City»= "Quebec" {IF«Receipt_Number»= "0" "Output for Quebec without Receipt_Number" "Output for Quebec with Receipt_Number"} {IF«Receipt_Number»= "0" "Output for Not Quebec without Receipt_Number" "Output for Not Quebec with Receipt_Number"}}

thanks again
