Hi, try this

Sub SelectDataRange() ' from A1 find used range
    Dim LastRow As Long, LastColumn As Long
    Dim MyRange As Range
    Sheets("Entry").Select

    'Find the used range
    LastRow = Cells.Find(What:="*", After:=Range("A1"), SearchOrder:=xlByRows, SearchDirection:=xlPrevious).Row
    LastColumn = Cells.Find(What:="*", After:=Range("A1"), SearchOrder:=xlByColumns, SearchDirection:=xlPrevious).Column

    'Set a range using the last row & column
    Set MyRange = Sheets("Entry").Range(Range("B3"), Cells(LastRow, LastColumn))
    
    'Copy the data
    MyRange.Copy Sheets("Dataset").Range("B2")
    MyRange.Copy Sheets("Dataset").Range("B12")
    
    Sheets("Dataset").Select
End Sub
With this macro you dont actually use the named ranges.
You find the used range from cell B3 in this case, it looks for the last row of data and the last column of data. It then assigns the cells B3:K7 to MyRange. Then you can copy that range to wherever you want. That way if you add another row of data, next time it will increase the range size and copy it to the same starting point cell i.e B2 & B12.
