Need URL formula link that displays a report from Table #1 while viewing records in Table #2

It's a real handy trick.

The nv=1 means and number of variables (ie questions =1), and the v0 means "and here is the answer to the 0th question" - its starts numbering at zero,

so if there were two <ask the user> questions it would read

&nv=2&v0=" & urlencode([field1])& "&v1=" & urlencode([field 2])
