ช่วยดูโค๊ดให้หน่อยคับมัน error Syntax error in INSERT INTO statement.

        dim sqladd as string = "insert into register(id_la,id_shop,code_label,wide,long,unit,relate)"
        sqladd &= " values ('" & TextBox1.Text & "',"
        sqladd &= "'" & TextBox2.Text & "',"
        sqladd &= "'" & ComboBox1.Text & "',"
        sqladd &= "'" & TextBox3.Text & "',"
        sqladd &= "'" & TextBox4.Text & "',"
        sqladd &= "'" & TextBox5.Text & "',"
        sqladd &= "'" & Label11.Text & "')"

        comm = New OleDbCommand
        With comm
            .CommandText = sqladd
            .CommandType = CommandType.Text
            .Connection = con
            .ExecuteNonQuery()
        End With
        MessageBox.Show("บันทึกข้อมูลเรียบร้อยแล้ว", "ยืนยันการบันทึก")
