Iterate through VBA dropdown list

I have three dropdown validation lists and I am trying to write some code that iterates through all of the "Management Methods" permutations that are available.

I can figure out the first step of iterating through one list (for example Iterate through an Excel dropdown/validation list and others) but I can't work out how to go through three of them.

Ideally, I would like this to be written in a way that works even if you add more options.

To achieve this I figure you want a way of counting how many options there are in each list and then iterating through from 0-n.

Any help would be much appreciated.

Sub LoopThroughList()
Dim Dropdown1, Dropdown2, Dropdown3 As String
Dim Range1, Range2, Range3 As Range
Dim option1, option2, option3 As Range

' *** SET DROPDOWN LOCATIONS HERE ***
' ***********************************

    Dropdown1 = "C6"
    Dropdown2 = "D6"
    Dropdown3 = "E6"

' ***********************************
' ***********************************

Set Range1 = Evaluate(Range(Dropdown1).Validation.Formula1)
Set Range2 = Evaluate(Range(Dropdown2).Validation.Formula1)
Set Range3 = Evaluate(Range(Dropdown3).Validation.Formula1)

For Each option1 In Range1
    For Each option2 In Range2
        For Each option3 In Range3

            Worksheets("Sheet1").Range("C6:E6").Copy
            With Sheets("Sheet2").Range("A" & Rows.Count).End(xlUp).Offset(1)
                .PasteSpecial Paste:=xlPasteColumnWidths
                .PasteSpecial Paste:=xlPasteValues
            End With


        Next option3
    Next option2
Next option1


End Sub

At the moment I get this:

This is iterating through the crop type dropdown but returning the same for pest and management methods. The code I used to create the dropdown list is as below:

Option Explicit

Private Sub Worksheet_Change(ByVal Target As Range)

    If Target.Cells.Count > 1 Then Exit Sub

    If Not Intersect(Target, Range("C6")) Is Nothing Then
        Range("D6:E6").ClearContents
    End If

End Sub

The easiest way to perform loops that will iterate through every possible combination is to use a For Each loop. You can find more info about them here and here and here and here....... !!! Etcetera....

This will loop through every combination of 3 dropdown lists. You will need to change the location of the dropdowns in my code.

Sub LoopThroughList()
Dim Dropdown1, Dropdown2, Dropdown3 As String
Dim Range1, Range2, Range3 As Range
Dim option1, option2, option3 As Range

' *** SET DROPDOWN LOCATIONS HERE ***
' ***********************************

    Dropdown1 = "D8"
    Dropdown2 = "E8"
    Dropdown3 = "F8"

' ***********************************
' ***********************************

Set Range1 = Evaluate(Range(Dropdown1).Validation.Formula1)
Set Range2 = Evaluate(Range(Dropdown2).Validation.Formula1)
Set Range3 = Evaluate(Range(Dropdown3).Validation.Formula1)

For Each option1 In Range1
    For Each option2 In Range2
        For Each option3 In Range3

            ' *** PERFORM CODE HERE ***
            ' EXAMPLE
            ' Sheets(1).Cells(1, 1) = option1
            ' Sheets(1).Cells(2, 1) = option2
            ' etc...

        Next option3
    Next option2
Next option1


End Sub

EDIT:

Sub LoopThroughList()
Dim Dropdown1, Dropdown2, Dropdown3 As String
Dim Range1, Range2, Range3 As Range
Dim option1, option2, option3 As Range

Dim Counter As Long

Counter = 1

' *** SET DROPDOWN LOCATIONS HERE ***
' ***********************************

    Dropdown1 = "C6"
    Dropdown2 = "D6"
    Dropdown3 = "E6"

' ***********************************
' ***********************************

Set Range1 = Evaluate(Range(Dropdown1).Validation.Formula1)
Set Range2 = Evaluate(Range(Dropdown2).Validation.Formula1)
Set Range3 = Evaluate(Range(Dropdown3).Validation.Formula1)

For Each option1 In Range1
    For Each option2 In Range2
        For Each option3 In Range3

            Sheets(2).Cells(Counter, 1) = option1
            Sheets(2).Cells(Counter, 2) = option2
            Sheets(2).Cells(Counter, 3) = option3
            Counter = Counter + 1

        Next option3
    Next option2
Next option1


End Sub
