I am trying to combine input from two text fields into a third field.
When I select the third field, I set it as "calculate" and then in the script line I choose FormCalc and then type in the following
TextField11 = Concat(ProjectNum, CPNumber)
FYI: all three fields are set as text fields, despite the fact I have called them numbers)
When I run the form I receive the message
...Error: accessor 'ProjectNum' is unknown.
How do I join ProjectNum to CPNumber to get a third field called TextField11?
