I am using sharepoint validation control to validate only numbers but whatever i enter it says "please enter valid number". What is wrong with my validation expression?

<SharePoint:InputFormRegularExpressionValidator ID="NumberValidator"  runat="server" Display="Dynamic" SetFocusOnError="true"
                        ControlToValidate="txtMobile" BreakBefore="true" ErrorMessage="Please nter valid number"  ValidationExpression="^[0-9]$"/>

Your Regular Expression will only work for 1 digit. To accept 1 or more digits, change it to ^[0-9]+$. To accept 0 or more digits, change it to ^[0-9]*$
