val(text1.text) - Help Please (Financial Calculator)

Here is a snippet of my code for a financial calculator program. The Val(lstInterest.Text) works if the interest rate does not contain a number after the decimal point. (7.00%) However, if the text contains a number (7.25%), then I get a type mismatch error.

Any Ideas???

Code:

---

Dim MonPmt As Double, dblRate As Double, intPmts As Integer, dblPrncpl As Double

Public Sub Interest()
dblPrncpl = txtPrincipal.Text
dblRate = Val(lstInterest.Text)
dblRate = dblRate / 100
MonPmt = Pmt(dblRate / 12, intPmts, -dblPrncpl)
lblPayment = Format(MonPmt, "$###,###,##0.00")

End Sub
Private Sub cmdCalc_Click()

Interest

End Sub

Private Sub Form_Load()
    frmMthlyPay.Left = (Screen.Width - frmMthlyPay.Width) / 2
    frmMthlyPay.Top = (Screen.Height - frmMthlyPay.Height) / 2
End Sub


Private Sub mnuFileExit_Click()
End
End Sub

Private Sub mnuFilePrint_Click()
frmMthlyPay.PrintForm
End Sub

Private Sub mnuFormatBackground_Click()
dlgCommon.Flags = cdlCCRGBInit
dlgCommon.ShowColor
frmMthlyPay.BackColor = dlgCommon.Color
End Sub

Private Sub mnuFormatFont_Click()
dlgCommon.Flags = cdlCFBoth

dlgCommon.FontName = lblPayment.FontName
dlgCommon.FontBold = lblPayment.FontBold
dlgCommon.FontItalic = lblPayment.FontItalic
dlgCommon.FontSize = lblPayment.FontSize

lblPayment.FontName = dlgCommon.FontName
lblPayment.FontBold = dlgCommon.FontBold
lblPayment.FontItalic = dlgCommon.FontItalic
lblPayment.FontSize = dlgCommon.FontSize
dlgCommon.ShowFont
End Sub

Private Sub mnuFormatInfo_Click()
dlgCommon.Flags = cdlCCRGBInit
dlgCommon.ShowColor
fraInfo.BackColor = dlgCommon.Color
End Sub

Private Sub optTerm_Click(Index As Integer)
Select Case Index
Case 0
intPmts = 24
Case 1
intPmts = 36
Case 2
intPmts = 48
Case 3
intPmts = 60
End Select
End Sub

Where exactly? Type mismatches are very easy to track and get rid of, but i don't have your project so i can't tell you

It is on this line:

Code:

---

dblRate = Val(lstInterest)

---

The variable creating the problem contains a percentage number with more than a zero after the problem. There is no error message if the user inputs say 7.00%. But if the input is 7.25% then there is a type mismatch.

Hmmm
Thanks for the help,
Sal

It doesn't accept the "%" so you can do this:
dblRate = Val(left(lstInterest,len(lstInterest)-1))
