Code not working properly

Jot18 (7)
Can someone help me fix this code please???The days do increase but the organisms stay the same for each day....

question: Write a program that will predict the size of a population of organisms. The program
should ask the user for the starting number of organisms, their average daily population
increase (as a percentage of current population), and the number of days they will multiply.
A loop should display the size of the population for each day.
Input Validation: Do not accept a number less than two for the starting size of the
population. Do not accept a negative number for average daily population increase.
Do not accept a number less than one for the number of days they will multiply.

 #include <iostream>

using namespace std;

int main()
{
	int Organisms, Growth, Days;
	int Day = 0;

	do
	{
		cout << "Please enter the starting number of orgranisms: ";
		cin >> Organisms;
	if (Organisms < 2)
	{
		cout << "The starting number of organisms must be atleast 2\n";
	}
 }

	while (Organisms < 2);
	do
	{
		cout << "Please enter the amount of days to multiply: ";
		cin >> Days;
		if (Days < 1)
		{
			cout << "The amount of days must be greater than 1.\n";

	}
	while (Days < 2 );
	do

		cin >> Growth;
	if (Growth < 0)
	{
		cout << "The amount of growth must be greater than 0.\n";
	}
 }
	while ( Growth < 0);
	Growth/= 100;
	cout << "Day     Number of Organisms: " << endl;
		do
		{ 
			cout << setw(2) << Day << setw(20) << Organisms << endl;
		((1 + Growth) * Organisms);
	
		Organisms = Organisms * (1 + Growth);
		Day++;
	}
	
		while ( Day <= Days );
	
	system ("Pause");
	return 0;
}

((1 + Growth) * Organisms); on line 47, don't think that'd do anything.

@Austin I got rid off that line and it still won't work...I'm obviously a noob and can you please tell me how to fix it?Thanks.

Well, your last while loop will never execute because you're only running it while growth is <0, but you force the user to enter a value >0. Try swapping that sign around.

@brett it didn't work..when i changed the signs and compiled it kept on asking me to enter the average population increase

No Keep the while condition as growth<0 only
Now does it work?
