java.sql.SQLException: [SQLITE_ERROR] SQL error or missing database (near "Name": syntax error)

I am doing a log in application in which users should be able to sign in. But I am getting this error:

java.sql.SQLException: [SQLITE_ERROR] SQL error or missing database (near "Name": syntax error)

This is how my code looks like:

saveTButton.addEventHandler(ActionEvent.ACTION, (e)-> {

        try
        {
            String query = "insert into TeachersInfo (First Name,Last Name,UserName,Password) values (?,?,?,?)";
            PreparedStatement pst = connectionUsers.prepareStatement(query);
            //First question mark = 1, second = 2, etc.
            pst.setString(1,nameSignupTTextField.getText());
            pst.setString(2,lastnameSignupTTextField.getText());
            pst.setString(3,usernameSignupTTextField.getText());
            pst.setString(4,passwordSignupTTextField.getText());


            pst.execute();

            System.out.println("Data saved");

            //after executing the query this lines will close the connection with the database
            pst.close();

        }
        catch(Exception a)
        {
            System.out.println(a);
        }
    });

The code should save the info entered by the user in the database. I have no idea what is the problem so I would really appreciate the help. Thank you in advance..
