vba to save as new workbook in current path using cell value as the new file name

[recreated1]

Hi,
I am a bit of a novice and have been trying to piece together a macro using code posted in the forum.
I am using Excel 2016
I am trying to create a save button that will save a new copy of the open workbook in the same directory path as the original, using the value in the first worksheet, Cell B2, as the new file name.
I have the following code but get a runtime error 1004 [Method 'SaveAs' of object'_Workbook' failed] on the red highlighted line.
Additionally, the original document contains the Macro so its an .xlsm format, and in the new document I want to disable the macro so saving as an .xlsx format
Can someone help me figure this out?
Thanks!!

Sub SaveAsNewFile()


    Dim relativePath As String, sname As String
    sname = ActiveWorkbook.Worksheets(Sheet1).Range("B2") & ".xlsx"
    relativePath = Application.ActiveWorkbook.Path & "\" & sname
    Application.DisplayAlerts = False
    ActiveWorkbook.CheckCompatibility = False
    ActiveWorkbook.SaveAs FileName:=relativePath, FileFormat:=51
    Application.DisplayAlerts = True
End Sub
