Why does this VBA code give me an Object Required error?

Question

I have the following code in an Excel macro:

Dim cellRange As range
Dim cell As range
Dim cellFormula As String
Dim yearCells As New Collection

For Each cellRange In ranges
    For Each cell In cellRange.Cells
        cellFormula = GetCellFormula(cell)
        If (cellFormula = formulaYears) Then
            yearCells.Add (cell)
        End If
    Next
Next

Where ranges is a Collection object holding many Range objects.

When I run the code, I get an "Object required" error on the line For Each cellRange In ranges . Why is this? After all, cellRange is declared as an object, ie Dim cellRange As range . If I convert the code to a For loop, I have the same error on a line:

Set cellRange = ranges(i)

BTW, my VBA IDE insists on range always having a lower case initial letter. When I type Range the editor "corrects" it to range . Yet other code using range objects works fine.

Answer 1

The answer lays in the way you populate your collection I'm sure. For example see the following:

Sub Test()

Dim ranges As New Collection
Dim rng1 As Range, rng2 As Range, rng3 As Range
Dim cellRange As Range, cell As Range

Set rng1 = Range("A1:A3")
Set rng2 = Range("B1:B3")
Set rng3 = Range("C1:C3")

ranges.Add rng1
ranges.Add rng2
ranges.Add rng3

For Each cellRange In ranges
    Debug.Print cellRange.Address
    For Each cell In cellRange
        Debug.Print cell.Address
    Next cell
Next

End Sub
