Pass Array Elements To Private UserForm Module

I am trying to pass a string array into a form. I have added a member string array to the form, and a property to "Let" the array in the the member array.


Private sFormString() As String

Property Let FormString(value() As String)
sFormString = value
End Property

I can pass a string in using a procedure:


Sub StringArrayTest1()

Dim TestString() As String
Dim frmString As FString

but I cannot "modulate" the code, or else I get an internal error (error 51). I.e. this code doesn't work:



Sub StringArrayTest2Mod(TestString() As String, frmString As FString)

frmString.FormString = TestString

End Sub

Sub StringArrayTest2()

Dim TestString() As String
Dim frmString As FString

Set frmString = New FString
Redim TestString(1 To 2)
TestString(1) = "Cat"
TestString(2) = "Dog"

Call StringArrayTest2Mod(TestString, frmString)

End Sub

Does anyone know why this happens? Obviously, in the example code its not an issue, but the application I'm using this for is more complex, and some modulation here would be good.
