Question : Perl CGI using Frames

I have a page that shows 3 frames that are created from a .pl file. The way I need it to work is when the home.pl is started it builds the frames them load a list of tables from a database with checkboxes into Frame 1.  Frame 2 is the search page. This has forms that need to be populated based on what is checked in Frame 1. Basically it will add to a form a list of column headers from the selected table. There will be other boolean options built in as well. Frame 3 will display the results of the search from Frame 2. My real question is:
+++++++ ++++++++++++++++++
+            + +      Frame2                     +
+ Frame1+ +                                      +
+            + +                                       +
+            + ++++++++++++++++++
+            + ++++++++++++++++++
+            + +       Frame3                    +
+            + +                                       +
+            + +                                       +
+++++++ ++++++++++++++++++
As the users selects items from the list, I want to automatically populate a form in Frame 2. I don't want to have the users press any add or submit buttons.

Is this possible and any directions on how to approach this would be appreciated!

-Thanks

Answer : Perl CGI using Frames

I figured it out, here was my change:
    my $sth= $connection->prepare($set_select) or die "$DBI::errstr\n";
    @props= $sth->execute() or die "$DBI::errstr\n";

Off to more problems now...

Thanks for all the input!
