I have a WSS form (newform.aspx) that once the user fills out the form
is then redirected to another web part page. This works fine but I
would also like to pass the values of 3 form fields to the web part
page (page1.aspx) via the URL.

On the bottom of the newform.aspx page, I have the following:

<input type="hidden" name="NextUsing" id="NextUsing"
value="page1.aspx"

Is it possible to build a string to include the form values to be
passed to a web part page? Any ideas would be greatly appreciated.
Thank you.
