So I made a working bit of code (javascript) to validate a Terms Of Use checkbox.

When the checkbox and CustomValidator are inside The "CreateUserWizard" form It won't work.

Outside it, there's no problems. My code is:

<asp:CheckBox ID="AcceptTermsCheckBox" runat="server" Text="&nbsp;I agree to the Detelli Property Network"

Font-Size="8" ForeColor="#133792" ValidationGroup="CreateUserWizardControl" /><br />

&nbsp;<asp:HyperLink runat="server" NavigateUrl="Terms.aspx"

ForeColor="#133792" Font-Underline="true" ID="Terms" Font-Size="8">terms of use.</asp:HyperLink><br />

<asp:CustomValidator ID="ValTermsCheckBox" ClientValidationFunction="AcceptTermsCheckBoxValidation"

runat="server" ErrorMessage="Please accept Terms and Conditions." ValidationGroup="CreateUserWizardControl" OnServerValidate="ValTermsCheckBox_ServerValidate">

</asp:CustomValidator>

And my javascript code, that I can only place outside the "CreateUserWizard" form, is:

<script language="javascript" type="text/javascript">

function AcceptTermsCheckBoxValidation(source, args)

args.IsValid = document.getElementById('<%= AcceptTermsCheckBox.ClientID %>').checked;

</script>

I've been trying to write some Visual Basic in the code behind that I can use,

but it's not working, no matter what I do it pulls up the error as though the checkbox is unchecked. 

Protected Sub ValTermsCheckBox_ServerValidate(ByVal source As Object, ByVal args As System.Web.UI.WebControls.ServerValidateEventArgs)

Dim AcceptTermsCheckBox As CheckBox = CreateUserWizardStep1.Controls(0).FindControl("AcceptTermsCheckBox")

If AcceptTermsCheckBox.Checked = True Then

args.IsValid = True

End If

End Sub

This is really leaving me stumped, any ideas would be greatly appreciated. 

Thank you in advance
