[John Colby]

A ParamArray is not a string, it is an array of parameters.

Sub AnyNumberArgs2(strName As String, ParamArray intScores() As Variant)
 Dim varParam As Variant

 Debug.Print strName; " Scores"
 ' Use UBound function to determine upper limit of array.
 For Each varParam In intScores()
    Debug.Print " "; varParam
 Next varParam
End Sub

AnyNumberArgs2 "Jamie", 10, 26, 32, 15, 22, 24, 16
Jamie Scores
  10
  26
  32
  15
  22
  24
  16

AnyNumberArgs2 "Kelly", "High", "Low", "Average", "High"
