I need help!
The errors I got
error: INTEREST_PER_YEAR not declared
error: PAYMENTS_PER_YEAR not declared
error: intPerPayment not declared

Here is the code in Visual Web Devoloper 2005 Express

Code:

        'Create variables to hold the values entered by the user
        Dim P As Double = loanAmount.Text
        Dim r As Double = rate.Text / 100
        Dim t As Double = mortgageLength.Text

        Dim ratePerPeriod As Double
        ratePerPeriod = r / INTEREST_PER_YEAR

        Dim payPeriods As Integer
        payPeriods = t * PAYMENTS_PER_YEAR

        Dim annualRate As Double
        annualRate = Math.Exp(INTERESt_CALCS_PER_YEAR * Math.Log(1 + ratePerPeriod)) - 1

        Dim intPerPayment As Double
        intPerPayment = (Math.Exp(Math.Log(annualRate + 1) / payPeriods) - 1) * payPeriods

        'Now compute the total cost of the loan
        Dim intPerMonth As Double = intPerPayment / PAYMENTS_PER_YEAR

        Dim costPerMonth As Double
        costPerMonth = P * intPerMonth / (1 - Math.Pow(interPerMonth + 1, -payPeriods))

The problem is exactly what the error message says: INTEREST_PER_YEAR is not declared.

You're using this constant / variable, without declaring. What makes you think it can be used? Did you define it elsewhere?

You could declare it in your code as follows:

Dim INTEREST_PER_YEAR As Double = 4
