MySQL error: Column count doesn't match value count at row 1

Question

I am attempting to insert a new row into a MySQL database. However I am receiving

java.sql.SQLException: Column count doesn't match value count at row 1

each time I run the following piece of code.

JButton btnSubmit = new JButton("Submit");
    btnSubmit.addActionListener(new ActionListener() {
        Connection connection = dbConnector.dbConnector();
        public void actionPerformed(ActionEvent arg0) {
            try{
            String query = "insert into ChampionData(`Champion`,`User`,`TimeStamp`,`Opponet`,`Lane`,`Role`,`Kills`,`Deaths`,`Assists`,`CS`,`Gold`,`W/L`,`TotalGameTime`) values(?,?,?,?,?,?,?,?,?,?,?,?)";
            PreparedStatement pstInsert = connection.prepareStatement(query);
            pstInsert.setString(1, textField.getText());
            pstInsert.setString(2, textField_1.getText());
            pstInsert.setString(3, textField_2.getText());
            pstInsert.setString(4, textField_3.getText());
            pstInsert.setString(5, textField_4.getText());
            pstInsert.setString(6, textField_5.getText());
            pstInsert.setString(7, textField_6.getText());
            pstInsert.setString(8, textField_7.getText());
            pstInsert.setString(9, textField_8.getText());
            pstInsert.setString(10, textField_9.getText());
            pstInsert.setString(11, textField_10.getText());
            pstInsert.setString(12, textField_11.getText());
            pstInsert.execute();

            }catch(Exception e){
                e.printStackTrace();
            }
        }
    });

Error received each time the code is executed.

The problem is with this line:

String query = "insert into ChampionData(`Champion`,`User`,`TimeStamp`,`Opponet`,`Lane`,`Role`,`Kills`,`Deaths`,`Assists`,`CS`,`Gold`,`W/L`,`TotalGameTime`) values(?,?,?,?,?,?,?,?,?,?,?,?)";

The table ChampionData has 13 columns:

`Champion`
`User`
`TimeStamp`
`Opponet`
`Lane`
`Role`
`Kills`
`Deaths`
`Assists`
`CS`
`Gold`
`W/L`
`TotalGameTime`

While the row you're trying to insert has only 12 columns (as evidenced by the 12 question marks)
