Hi I have a textbox which can accept the following:
- Floating point number between 0 and 1
- It can go ONLY up to 2 decimal places(so either one decimal or two decimal.
- Will accept plain 0 or 1 without decimal
- Will not accept anything above 1.0, so it will not be able to accept 1.01.

how can I write a regular expression for this? Please help me. Thank you.

If you just need a simple test like that you can always use something like this:

<%
    Dim theDouble as double
    theDouble = 0.789
    If theDouble >= 0 and theDouble <= 1 Then
    Response.Write("<br />This number is good.")
    Else
    Response.Write("<br />This number is bad.")
    End If

%>
