Peace be upon you and good morning. I was trying to make a PTPTN loan calculator that calculate the required monthly payment accordingly. But when I tried to print into the text box, it only exist for a line. The vbNewLine or vbcrlf didn't seems to work. The following is my code. Is there any limitation in using vbNewline that I need to know? I also accept any other suggestion or advice regarding my code as I am still learning.

'PTPTN
'Calculate the amount that a student must pay every month to pay for their PTPTN study loan.
' Look for:
' 1. PTPTN interest rate = 1% per annum
' 2. Principle = RM 12,500
' 3. Years to pay < 10 years
'E.g.:
'Year  | Monthly Payment(RM) | Balance Payment(RM)
' 1    |                     |     12625
' 2
' Expected to have looping to display part.
'Formula :
'interest = principle * interestRate/100
'yearlyPayment = principle / yearsToPay
'monthlyPayment = (yearlyPayment + interest)/12
'totalPayment = totalPayment yearlyPayment
Option Explicit
Dim interest, interestRate, totalPayment, principle, yearlyPayment, monthlyPayment As Double
Dim yearsToPay, yearCounter As Integer
Dim stringCounter As String
Const monthPerYear As Integer = 12

Private Sub cmdCalculate_Click()
    interestRate = txtInterestRate.Text
    principle = txtTotalLoan.Text
    yearsToPay = txtYears2Pay.Text
    On Error GoTo errorLabel1 'errorchecking
    totalPayment = principle
    yearlyPayment = principle / yearsToPay
    
    interest = interestRate / 100 * principle
    
    stringCounter = "Year" & vbTab & "Monthly Payment(RM)" & vbTab & "Balance Payment(RM)"
    stringCounter = stringCounter & vbNewLine
    
    For yearCounter = 1 To 10
        monthlyPayment = (yearlyPayment + interest) / monthPerYear
        totalPayment = totalPayment - yearlyPayment
        stringCounter = stringCounter & yearCounter & vbTab & monthlyPayment & vbTab & totalPayment & vbNewLine
    Next
    txtDisplay.Text = stringCounter
    txtTotalLoan.Enabled = False
    txtYears2Pay.Enabled = False
    cmdCalculate.Enabled = False
    txtDisplay.Enabled = True
    Exit Sub
errorLabel1: 'end when have error
    MsgBox "Error! Please try again."
End Sub

Private Sub cmdClear_Click()
    interest = interestRate = totalPayment = principle = yearlyPayment = monthlyPayment = yearsToPay = 0
    txtYears2Pay.Text = "0"
    txtTotalLoan.Text = "0"
    txtDisplay.Text = ""
    txtTotalLoan.Enabled = True
    txtYears2Pay.Enabled = True
    cmdCalculate.Enabled = True
    txtDisplay.Enabled = False
    MsgBox "Cleared!"
End Sub

Private Sub cmdExit_Click()
    MsgBox "Have a great day! ^_^/>"
    End
End Sub

Private Sub Form_Load()
    MsgBox "Hello! :)/>"
End Sub

Edit Controls (Text Boxes) are single line by default. You have to change it to multiline for carriage returns to show multiple lines. Click on your text box, and somewhere in the properties list change multi line to true.
