Filter and List Mode - How can I change the initial category displayed?

[m2m]

I've got the filter installed on a list view page, but I'd like to have another page just like this one (http://companyofexperts.net/testing/events.php ) with on difference: it would display a different initital category. I've added "$showCat="1";" before require("calendar... So the right category is displayed on my new page (http://companyofexperts.net/testing/eventsDCI.php ). But now it's the only category info that's display despite changing the filter drop down and hitting submit.

How do I get the filter work (allowing to filter all categories) and change the initial displayed category?

Thanks in advance!

if(!isset($_REQUEST['showCat'])) $showCat="1";

Thanks! You are awesome!

I also figured out that all I really needed was to provide a link: http://companyofexperts.net/events.p...&Submit=Filter

Thanks again.
