iOs - Ribbit Project - DB on parse.com not updated with "friendsRelation" column?

I'm at the very end of the video, "Adding Friends by Tapping on a Table View Cell" and I'm fairly certain that I have followed every step exactly as shown, but tapping on a friend on the "Edit Friends" Table View adds a checkmark, but does not add the "friendsRelation" column to my parse.com database. I am not seeing any errors, and I don't really have debugging down yet :/

(I apologize for including everything, I'm not really comfortable enough with Objective-C to know what's pertinent)

EditFriendsTableViewController.h

#import <UIKit/UIKit.h>
#import <Parse/Parse.h>

@interface EditFriendsTableViewController : UITableViewController

@property (nonatomic, strong) NSArray *allUsers;
@property (nonatomic, strong) PFUser *currentUser;


@end

EditFriendsTableViewController.m

#import "EditFriendsTableViewController.h"

@interface EditFriendsTableViewController ()

@end

@implementation EditFriendsTableViewController

- (void)viewDidLoad
{
    [super viewDidLoad];
    PFQuery *query = [PFUser query];
    [query orderByAscending:@"username"];
    [query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
        if (error) {
            NSLog(@"Error: %@ %@", error, [error userInfo]);
        }
        else {
            self.allUsers = objects;
            [self.tableView reloadData];
        }
    }];

    self.currentUser = [PFUser currentUser];
}

#pragma mark - Table view data source

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{

    // Return the number of sections.
    return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{


    return self.allUsers.count;
}


- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"Cell" forIndexPath:indexPath];

    PFUser *user = [self.allUsers objectAtIndex:indexPath.row];
    cell.textLabel.text = user.username;

    return cell;
}

#pragma mark - Table view delegate

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

    UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
    cell.accessoryType = UITableViewCellAccessoryCheckmark;

    PFRelation *friendsRelation = [self.currentUser relationForKey:@"friendsRelation"];
    PFUser *user = [self.allUsers objectAtIndex:indexPath.row];
    [friendsRelation addObject:user];
    [self.currentUser saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
        if (error) {
            NSLog(@"Error: %@ %@", error, [error userInfo]);
        }
    }];

}

@end

Whoops.. Wow I'm dumb... My browser window was resized too small, it was out of view on parse.com, and somehow I didn't notice the 2nd scrollbar. I just wasted like 3 hours troubleshooting! Can I delete this thread? ;)
