Code / Description
In the default value of a field, use this formula to assign the next consecutive number using an environment variable: REM "Retrieve last number from the Environment variable"; Temp := @Environment("Num"); REM "Start with zero if the Environment variable came back blank"; Temp2 := @If(Temp = ""; "00000"; Temp); REM "Change to numeric"; CurrentNum := @TextToNumber(Temp2); REM "Add one to get the next number"; NextNum := CurrentNum + 1; REM "Calculate number of zeroes you need to pad with to get a five-digit number"; Zeroes := (NextNum < 10000) + (NextNum < 1000) + (NextNum < 100) + (NextNum < 10); REM "Assign and save the number - converting it back to text"; ENVIRONMENT Num := @Repeat("0"; Zeroes) + @Text(NextNum); REM "Return the new number as a text string"; Num

Set the field as computed when compose...It's really works!
