If, else if and else statements

[b1gzz]

I was just having fun with these statements when I came across an error:

int main(){
	unsigned int fstNumb = 0, sndNumb = 0;
	cout << "Choose the first number: ";
	cin >> fstNumb;
	cout << "\nChoose the second number: ";
	cin >> sndNumb;
	cout << "\nNow click \'m\' to multiply, \'a\' to add or \'d\' to divide: ";
	char option = '\0';
	cin >> option; cout << "\n\n";
	float result;
	if (option == 'm'){
		result = fstNumb * sndNumb;
		cout << result;
	} 
	else if (option == 'a'){
		result = fstNumb + sndNumb;
		cout << result;
	}
	else if (option == 'd') {
		if (fstNumb || sndNumb == 0)
			cout << "Cannot divide with 0 :/";
		else
			cout << "You want the " << fstNumb << " or " << sndNumb << " to be divided?\n";
			cout << "Press 1 for " << fstNumb << " or 2 for " << sndNumb;
			char option2 = '\0';
			cin >> option2;
			if (option2 == 1)
				cout << "\nYou chose " << fstNumb;
				cout << "\nWanna divide it by how much?: ";
				unsigned short division;
				cin >> division;
				result = fstNumb / division;
			else if (option2 == 2){
				cout << "\nYou chose " << sndNumb;
				cout << "\nWanna divide it by how much?: ";
				unsigned short division;
				cin >> division;
				result = sndNumb / division;
			}
			else
				cout << "You must choose one of those 2 numbers!\n";
	}
	else
		cout << "That's none of the letters I asked you.\n";
}

On line 33 my compiler says "Illegal else without matching if", is it illegal to put else if's inside of an else statement?
Don't mind with the rest of the code :p

Thanks

line 23 put curly braces because if you dont your else ends at the first statement cout << "You want the " << fstNumb << " or " << sndNumb << " to be divided?\n";

Oh, I thought that using or not the brackets wouldn't make any difference but seems like it does :o
Thanks.
