I am trying to insert a row into a table (userGames), using Ucanaccess, and, when executing the statement, am recieving the following error:

In my connect class, i have the following:
private Connection conn;
public Connect(String filepath) {
try {
Class.forName("net.ucanaccess.jdbc.UcanaccessDriver");
conn = DriverManager.getConnection("jdbc:ucanaccess://" + filepath + ";");
System.out.println("Connection successful");
} catch (Exception e) {
System.out.println("ERROR: " + e);
e.printStackTrace();
}
}
and the update/insert method:
public boolean update(String sql) {
boolean result = false;
try {
Statement stmt = conn.createStatement();
result = stmt.execute(sql);
} catch (SQLException ex) {
Logger.getLogger(Connect.class.getName()).log(Level.SEVERE, null, ex);
}
return result;
}
I am sending the following SQL statement to the update method:
"INSERT INTO userGames (userID,gameID) VALUES ("+users[id]+","+games[i]+")"
I have no idea what an "unknown token" is, or what I should do to rectify the error.
I have read the guide for Ucanaccess, and they do the same thing as I am doing, as far as I can see. Both .execute and .executeUpdate throw this error, and I do not know what to do.
Thanks for any help
