Expected Expression iOS Xcode - iphone

Question

I'm trying to make a simple Calculator App and I'm following instructions in this video ( https://www.youtube.com/watch?v=Uzq41DRC0-Q )
However, when i got to about 9:14, I got an error saying "Expected Expression" and some mark before the else statement. I cannot post images now, so post me everything you know, please. I'm a newbie, so any help would be appreciated!
My code (ViewController.m) :
#import "ViewController.h"
#interface ViewController ()
#end
#implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
}
- (IBAction)ClearPressed:(id)sender {
}
- (IBAction)MinusPressed:(id)sender {
}
- (IBAction)PlusPressed:(id)sender {
}
- (IBAction)EqualsPressed:(id)sender {
}
- (IBAction)NumberPressed:(UIButton*)sender;{
NSInteger tag = sender.tag;
if (operatorPressed == FALSE) {
if (firstEntry == NULL) {
firstEntry = [NSString stringWithFormat:#"%li", (long)tag];
_OutputLabel.text = firstEntry;
}
}
else {
firstEntry = [NSString stringWithFormat:#"%#%li",firstEntry ,(long)tag];
_OutputLabel.text = firstEntry;
}
else { //HERE MY PROBLEM IS
if (secondEntry == NULL) {
secondEntry = [NSString stringWithFormat:#"%li", (long)tag];
_OutputLabel.text = secondEntry;
}
else {
if secondEntry = [NSString stringWithFormat:#"%#%li",firstEntry ,(long)tag];
_OutputLabel.text = secondEntry;
}
}
}
#end

You have two else statements. That's a no no.
- (IBAction)NumberPressed:(UIButton*)sender;{
NSInteger tag = sender.tag;
if (operatorPressed == FALSE) {
if (firstEntry == NULL) {
firstEntry = [NSString stringWithFormat:#"%li", (long)tag];
_OutputLabel.text = firstEntry;
}
}
else { // 1
firstEntry = [NSString stringWithFormat:#"%#%li",firstEntry ,(long)tag];
_OutputLabel.text = firstEntry;
}
else { // 2
if (secondEntry == NULL) {
secondEntry = [NSString stringWithFormat:#"%li", (long)tag];
_OutputLabel.text = secondEntry;
}
else {
if secondEntry = [NSString stringWithFormat:#"%#%li",firstEntry ,(long)tag];
_OutputLabel.text = secondEntry;
}
}
}
Check where I marked off with 1 and 2. The first else should be else if (someCondition). You can't have two else statements.
