Output Access 2007 Report to PDF generates Error 2282

Using the attached code I am trying to output a report to a pdf file in a specific location. The code generates however error 2282. "The format in which you are attempting to output the current object is not available."  Is it possible to do what I am attempting? Thank you.

Function TestPotRpt()

    Dim DateSuf As String
    Dim FPath As String
    Dim FName As String
    Dim FPN As String
    Dim Yr As String
       
    'Create DateSuf
    If InStr(1, Date, "/") = 2 And InStr(3, Date, "/") = 4 Then
        DateSuf = 0 & Month(Date) & 0 & Day(Date) & Format(Date, "yy")
    ElseIf InStr(1, Date, "/") = 2 And InStr(3, Date, "/") = 5 Then
        DateSuf = 0 & Month(Date) & Day(Date) & Format(Date, "yy")
    ElseIf InStr(1, Date, "/") = 3 And InStr(4, Date, "/") = 5 Then
       DateSuf = Month(Date) & 0 & Day(Date) & Format(Date, "yy")
    Else
        DateSuf = Month(Date) & Day(Date) & Format(Date, "yy")
    End If
    
    FPath = "\\Kermit\Potential\"
    
    FName = "PotDol"
    
    FPN = FPath & FName & DateSuf & ".pdf"
    

    DoCmd.OpenForm ("frmPot")   'Provide report date ranges
    DoCmd.OutputTo acOutputReport, "rptPotDaily2", acFormatPDF, FPN

End Function
