Eu estou tentando escrever um programa onde eu posso gravar dados para um banco de dados do Access, mas continuo recebendo o erro "Erro de sintaxe na instrução INSERT INTO".

FirstLast é o nome da tabela;First eLast são colunas nele.

Imports System.Data.OleDb

Public Class Form1
    Dim theConnectionString As New OleDbConnection
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        theConnectionString.ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Users\user\Documents\Database1.accdb"

        Dim cmd As OleDbCommand = New OleDbCommand("INSERT INTO FirstLast (First, Last) VALUES (@First, TextBox1.text)", theConnectionString)

        cmd.Parameters.Add("@First", OleDbType.Char, 255).Value = TextBox1.Text
        cmd.Parameters.Add("@Last", OleDbType.Char, 255).Value = TextBox1.Text

        Try
            theConnectionString.Open()
            cmd.ExecuteNonQuery()
        Catch ex As Exception
            Throw ex
        Finally
            theConnectionString.Close()
        End Try

    End Sub
End Class
