Redirecting from ASP Form Handler

I've got a form contained within an ASP file that uses another ASP as the handler.  Within the handler, I've attempted to use:
<%Response.Redirect "EFIAIR_disp_volt.asp" %> to go back to the ASP form page that called the handler.  I receive no error and the redirection does not work.  The frame remains on the handler.asp.
I've used 'Creating a Data Entry Form' in the Visual Developer Studio as an example.
Thanks in advance.
