Formatting and Validation Options for a Form: go() versus call()

Question

Hello.
Under a Form's "Formatting and Validation Options," the screen says:
"On successful submission of a form, execute this PL/SQL block or PL/SQL procedure:
Hint: You can redirect your browser to a PL/SQL procedure, for example a procedure that creates a Web page, using either of these methods:
call('<url>', '<parameter name for back url>');
Redirects the browser to the procedure and passes a parameter containing the URL back to the form.
go('<url>');
Redirects the browser to the procedure but does not pass a URL to return to the form."
I can get the go() procedure to work but not the call(). Here are the particulars:
1. I created a simple page.
2. I created a Form and placed it on the page.
3. I have PL/SQL code added to the "On successful submission of a form..." section of the Form so that when the user enters a transaction this code executes.
4. Unfortunately, the go() procedure redisplays the Form but not the underlying page.
I'm guessing (hoping) that if I can properly format the call() procedure instead, it will successfully display the underlying page and this Form. But no matter how I format the second parameter of the call() procedure I get the error "HTTP 400 Bad Request" "The web page cannot be found"
Can anyone provide a simple, working example for the call() procedure? Thanks for any insight.
