Flaging a duplication

Flaging a duplication

Flaging a duplication

Hi, I am a newbe here and a novice to Pdox programming.  
Problem: I designed a little database, using Pdx9, by linking three tables by a primary key field, FileNum;it works fine.  However, I need this code verified that would flag the user if he enters a duplicate FineNum.  FileNum is of type Alpha; eg. AC1052

Any help would be greatly appreciated.

method changeValue(var eventInfo ValueEvent)


    tc TCursor

    NewFileNum string      ; new file number


    NewFileNum = eventInfo.newValue()           ;new file number gets newValue                                  

     tc.open("Clients.db")  ; open database
         if NewFileNum <> "FileNum" then      ; is new file number found in database?
                                                         ; if so, display message.

                                                        ;[This line is NOT working when I use the "=" sign
                                                        ;to compare the variables]

             msgStop("Error !!", "Duplicate FileNum  "
             + NewFileNum
             + "   detected. Please use a unique FileNum or press Esc to cancel.")
