Runtime error '424' when running SQL

Question

I’m trying to send data from excel to access through a macro. I edited on top of a ready and it seemed to me that I was doing the same thing, but it gives "Error at runtime 424 - the object is mandatory" when it arrives in the "Execute SQL" part. I can’t find my mistake.

Sub Insere()
Dim gConexao As ADODB.Connection
a2019 = Cells(2, 2).Value
a2020 = Cells(2, 3).Value
a2021 = Cells(2, 4).Value
a2022 = Cells(2, 5).Value
a2023 = Cells(2, 6).Value
a2024 = Cells(2, 7).Value
lsInserir a2019, a2020, a2021, a2022, a2023, a2024
End Sub


Sub lsInserir(a2019, a2020, a2021, _
                      a2022, a2023, a2024)
    Dim lSQL As String

    lsConectar
 lSQL = "INSERT INTO Tabela1 &(a2019, a2020, a2021, a2022, a2023, a2024)" & _
    "VALUES (" & a2019 & "," & a2020 & "," & a2021 & "," & a2022 & "," & a2023 & "," & a2024 & ")"

    gConexao.Execute lSQL
    lsDesconectar
End Sub

Sub lsConectar()
    Dim strConexao As String
    Set gConexao = New ADODB.Connection

    strConexao = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Users\2005866\Documents\testeleituradados.accdb;Persist Security Info=False"

    gConexao.Open strConexao
End Sub

Sub lsDesconectar()
    If Not gConexao Is Nothing Then
        gConexao.Close
        Set gConexao = Nothing
    End If
End Sub
