Invalid Procedure call or argument on Debug.Print

Trying to redo a function I made a few days ago using some advice I received on here...I get an Invalid Procedure call or argument on the line with Debug.Print.

Very new to VBA and Excel. Thanks for your help and patience.

Public Sub GetSOPFiles()
    ' Set folder path
    Const FolderPath As String = "C:\Users\test\Desktop\SOP Excel Prototype"

    Const FileExt As String = "docx"

    Dim Result As Variant
    Dim i As Integer
    Dim MyFile As Object
    Dim MyFSO As Object
    Dim MyFolder As Object
    Dim MyFiles As Object
    Dim dept As Variant
    Dim deptCodes As Variant

    Set MyFSO = CreateObject("Scripting.FileSystemObject")
    Set MyFolder = MyFSO.GetFolder(FolderPath)
    Set MyFiles = MyFolder.Files

    Dim vData As Variant
    Dim sTemp As Variant

    ReDim vData(0 To MyFiles.Count - 1, 0 To 0)

    x = 1

    With MyFiles
        While x <= UBound(vData, 1)
            Debug.Print (MyFiles(x).Name)
        Wend
    End With
End Sub
