Hi experts,
I am having problem in "converting String to Decimal."
I worte a simple function that gets values from text boxes.
It makes a calculation and returns a value.
The code is written below.
The funny thing is whent I enter values 1, xxxx, 4 , it returned 96, but when I tried 1, xxxx, 4.5 I have got "Cast from string "4.5" to type 'Decimal' is not valid." error.
How do we convert String to Decimal? please help me

<%@ Page Language="

<%@ Import NameSpace="System.Data" %>
<script runat="server">
sub Submit(Sender as Object , e as EventArgs)
Calculate(tbUserID.Text,tbPayee.Text, tbAmount.Text)
End sub
public function Calculate(UseId as Integer, payee as String, decAmount as Decimal) As String
dim tempdecAmount as decimal
tempdecAmount = Convert.ToDecimal(decAmount)
response.write(useID)
response.write(payee)
dim Balance as Decimal
if tempdecAmount <= 100 then
Balance = 100 - tempdecAmount
