I need to build a Loan Calculator that uses functions to provide the values, for the text boxes, based on what radio button is clicked. Then i need to use a Sub to report the result with a label.
I think i am started off in the right direction but i have no background in vb so please bear with me.
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim Payment As Double
Dim Nper As Double
Dim LoanIRate As Double
Dim LoanDuration As Integer
Dim LoanAmount As Integer
If rdbmp1.Checked Then
Payment = Pmt(LoanIRate, LoanDuration, -LoanAmount, 0, )
TextBox4.Text = Payment.ToString("#.00")
End If
If rdbamt1.Checked Then
LoanAmount = PV(LoanIRate / 1200, LoanDuration, -Payment)
TextBox1.Text = Payment.ToString("#.00")
End If
If rdbir1.Checked Then
LoanIRate = 1200 * Rate(LoanDuration, Payment - LoanAmount)
TextBox2.Text = Payment.ToString("#.00")
End If
If rdbdl1.Checked Then
LoanDuration = Nper(LoanIRate / 1200, Payment, -LoanAmount)
TextBox3.Text = Payment.ToString("#.00")
End If
End Sub
At the moment the only calculation that is working for me correctly is the monthly payment, all of the others have build errors.

Provide the code for your functions.
