Code Challenge Help : Preparing user-to-user Push Notifications.

Challenge Task 5 of 5

Finally, set pushQuery to check where the "userId" field is equal to the playerId parameter. Hint: use the method whereEqualTo(String key, String value).

I keep reading this over and over to see where I'm going wrong in the code, but I can't figure out what's not right. I've tried putting playerId in quotes because it says String Value, but that makes even more errors.

``` java import android.app.Activity; import android.os.Bundle; import com.parse.ParseInstallation; import com.parse.ParseQuery;

public class InviteActivity extends Activity {

/*
 * Some code has been omitted for brevity!
 * This method gets called when an invitation is sent.
 */

public void sendPushNotifications(String playerId) {
 ParseQuery<ParseInstallation> pushQuery=ParseInstallation.getQuery();
 pushQuery whereEqualTo("userId", "playerId");

}

}```

Hi Ginger

The code should read as follows:

pushQuery.whereEqualTo("userId", playerId);

The double quotes are not required around the variable playerId, and you are missing the dot operator to call the whereEqualTo method of pushQuery
