what i am trying to do is this Display the mortgage payment amount and then list the loan balance and interest paid for each payment over the term of the loan. If the list would scroll off the screen, use loops to display a partial list, hesitate, and then display more of the list. below is the code i have .. i have the loan balance correct (i think) but i don't have the interest paid correct BUT when i run it the interest paid populates the same amount over and over. So can someone please help me with my interest paid issue, and the loops to display partially,hesitate and then more of the list?

```

package mortgagecalc;

I = the annual interest rate (from 1 to 100 percent)
L = length, the length (in years) of the loan, or at least the length over which the loan is amortized.
J = monthly interest in decimal form = I / (12 x 100)
N = number of months over which loan is amortized = L x 12
M = the monthly payment
M = P * ( J / (1 - (1 + J) ** -N))
Above are the definitions and terms to create an equation to calculate the mortgage payment.

Ok when i run it this is what i'm getting.

run:
