Can someone help me enter the code I need to achieve this.
Thanks very much for your help

<asp:RequiredFieldValidator id="rvForename" runat="server" ErrorMessage="A
Forename is required" ControlToValidate="add_Forename"

<asp:regularexpressionvalidator id="revlLengthLetter" ForeColor="Red"
Font-Size="Small" runat="server" ErrorMessage="Forename must be more than 2
and less than 25 characters and has to be a letter"
ControlToValidate="add_Forename" ValidationExpression="^[A-Za-z]{2,25}$">*
