How do I create a URL button on a QB Form that saves the current record and then displays a report?

I'm expecting that you would put this button on your report that you want to return to - which is the one with the <ask the user> question.  You might even suppress the regular edit button on the report and put in this as a little button as the first column of the report.

The "&nexturl=" part is undocumented but it seems to work in all the situations I have used it on so far.
