Hi Andy
Using VBScript you can use the IsNumeric
vb function to check for a number.
e.g.
Dim intNum
intNum = 5
'use
If IsNumeric(intNum) Then
...
End If
or
Dim intBasketQty
intBasketQty = Trim(Request.Form("txtBasketQty"))
If IsNumeric(intBasketQty) Then
... 'do something here
End If
Hope this helps

Hi
Thanx for trying to help.
What I'm doing is this - I have a shopping cart (I've had to write my own rather than use a commercial one to get some specific functionality) The form submits to itself and I pass through the querystring the form values.
I'm validating the form values ie checking that there is a value in various form fields in asp as the page loads.
I'm stuck on how to check that the qty value is a number and not text - I could do this client side with javascript but that would mean I'd have 2 validation routines, one client side and one server. If I have to move all validation client side I could, but if there is a simple solution to check for a number server side it would suit me better.
Regards
Andy G
