I am trying to pass a collection to a sub but I keep getting thi
error:

Compile Error:
Argument not optional

The collection is a collection of strings filled like this:
For i = 0 To finalrow - 3
assyNums(i) = Range("C" & i + 2)
Next i

I use this command to call the sub:
"Matching (assyNums)"
where Matching is the sub and, assyNums is collection.

The Sub looks like this:
"Private Sub Matching(assyNums)"
- OR - (if i add optional)
"Private Sub Matching(Optional assyNums)"

Inside the sub all i really do, is a for loop that accesses ever
element, so like
"For i = 0 To assyNums.Count"

Any help would be greatly appreciated

The construct you describe is an array, not a collection.

this worked for me:

Sub AB()
Dim assyNums() As String
Dim finalrow As Long
finalrow = Cells(Rows.Count, 3).End(xlUp).Row
ReDim assyNums(0 To finalrow - 1)
For i = 0 To finalrow - 3
assyNums(i) = Range("C" & i + 2)
Next i
Matching assyNums
End Sub

Private Sub Matching(assyNums() As String)
For i = LBound(assyNums) To UBound(assyNums)
Debug.Print i, assyNums(i)
Next
End Sub

Sub AB()
Dim assyNums() As Variant
Dim finalrow As Long
finalrow = Cells(Rows.Count, 3).End(xlUp).Row
ReDim assyNums(0 To finalrow - 1)
For i = 0 To finalrow - 3
set assyNums(i) = Range("C" & i + 2)
Next i
Matching assyNums
End Sub

Private Sub Matching(assyNums() As String)
For i = LBound(assyNums) To UBound(assyNums)
Debug.Print i, assyNums(i).Address(external:=True)
Next
End Sub

so you can hold objects in a variant array or an array dimensioned the same
type as the object or using the generic object type.


for a collection ( I use a Range object here, but you should be able to use
a user created object I would think

Sub AC()
Dim AssyNums As New Collection

For i = 1 To 10
AssyNums.Add Cells(i, 3), Cells(i, 3).Text
Next

Matching1 AssyNums
End Sub

Private Sub Matching1(AssyNums As Collection)
For Each itm In AssyNums
Debug.Print itm.Value
Next
End Sub
