Hi Leo,

Try this code.

Code:
Option Explicit
Sub kTest()
    
    Dim cboDDowns() As DropDown
    Dim i   As Long
    Dim c   As Long
    Dim wksSource   As Worksheet
    Dim wksDest     As Worksheet
    
    With Worksheets("Model Selection")
        c = .DropDowns.Count
        If c Then
            ReDim cboDDowns(1 To c)
            For i = 1 To c
                Set cboDDowns(i) = .DropDowns(i)
            Next
        End If
    End With
    
    For i = 1 To c
        Set wksSource = Worksheets(cboDDowns(i).List(cboDDowns(i).ListIndex))
        Set wksDest = Worksheets("Data" & i)
        wksDest.Range("a6:u" & wksDest.UsedRange.Rows.Count).ClearContents
        With wksSource
            .Range("a5:u" & .Range("a" & .Rows.Count).End(xlUp).Row).Copy wksDest.Range("a6")
        End With
    Next
    
End Sub
