Java Programming

Hello,

I've been attempting to write a small application that would compute the monthly payment for a loan. The program should work by requesting the user to input three variables, the loan amount, the interest rate, and the term of the loan in years. I've written a program that I thought would work, though every time I input the data it outputs an incorrect answer. So there must be a problem with my equation; more precisely the way I've attempted to input the equation into the code. I'll admit now, this is an assignment; so I'm not really looking for somebody to do this for me, instead I'd really appreciate some guidance as to where I've gone wrong.

Below I will provide you with my code, and a link to the assignment page with the full equation. I'd appreciate any help you could provide with this; Im just baffled. Thank you.

		{ Scanner sc = new Scanner(System.in) ;
			
			System.out.print("Please enter the loan amount: ");
			double LoanAmount = sc.nextDouble();
			
			System.out.print("Please enter the interest rate: ");
			double InterestRate = sc.nextDouble();
			
			System.out.print("Please enter the loan term in years: ");
			double LoanTerm = sc.nextDouble();
			
			double exponent = (-12 * LoanTerm);
			double MonthlyPayment = (LoanAmount * (InterestRate / 12)) / (1 - (1 + (InterestRate / 12)));
			double TMP = Math.pow(MonthlyPayment,exponent);
			
			System.out.println();
			System.out.println("Your monthly palyment is: " + TMP);
			System.out.println();
		}
