            MessageBox.Show("Сохранить?");
            //string query = "INSERT INTO awesome (work_name, salary, age_from, age_to, city, school, qwer, number) VALUES ('" + textBox1.Text + "', " + numericUpDown3.Value + ", " + numericUpDown2.Value + ", " + numericUpDown1.Value + ", '" + comboBox3.SelectedItem + "', '" + comboBox1.SelectedItem + "', '" + comboBox2.SelectedItem + "', '"+lol+"')";
            string query = "INSERT INTO awesome (work_name, salary, age_from, age_to, city, school, qwer, number) VALUES ('" + textBox1.Text + "', " + numericUpDown3.Value + ", " + numericUpDown2.Value + ", " + numericUpDown1.Value + ", '" + comboBox3.SelectedItem + "', '" + comboBox1.SelectedItem + "', '" + comboBox2.SelectedItem + "')";
            MessageBox.Show(query);

            command.ExecuteNonQuery();
            MessageBox.Show("Успешно сохранено!");
        }

Прошу обратить внимание на строчку

//string query = "INSERT INTO awesome (work_name, salary, age_from, age_to, city, school, qwer, number) VALUES ('" + textBox1.Text + "', " + numericUpDown3.Value + ", " + numericUpDown2.Value + ", " + numericUpDown1.Value + ", '" + comboBox3.SelectedItem + "', '" + comboBox1.SelectedItem + "', '" + comboBox2.SelectedItem + "', '"+lol+"')";
string query = "INSERT INTO awesome (work_name, salary, age_from, age_to, city, school, qwer, number) VALUES ('" + textBox1.Text + "', " + numericUpDown3.Value + ", " + numericUpDown2.Value + ", " + numericUpDown1.Value + ", '" + comboBox3.SelectedItem + "', '" + comboBox1.SelectedItem + "', '" + comboBox2.SelectedItem + "')";

То, что закомментено вызывает ошибку, то что не закоментенно соответственно не вызывает. Прошу объяснить, в каком месте ошибка.

Выдаваемая ошибка: System.Data.OleDb.OleDbException: "Ошибка синтаксиса в инструкции INSERT INTO."
