how do i create a dynamic user listing?

Im just getting into MODx and really enjoying it - but still not fully confident in how all the bits fit together, so i’m imagining this is actually a very simple question and would appreciate some help as to how it works! Heres my problem:

I have a list of members for a site, who are all located in different regions.
Regions are stored in the database in the ’modx_web_user_attributes_extended’ table under a ’region’ column with numerical values 1-5.
I want public visitors to the site to be able to see what members are in the each region and for that i have created a map with clickable areas.
I want to call the list, filtered by the region they have chosen when they click on the links in the map.

Firstly, what do i put as my link to call the regions from this snippet?
I’d like the map to display by default - when no region is requested - and the userlist to display when they click on the link
I am using seo-friendly urls, so the page i have the map on is: http://site.com/map.html

So should the link be something like http://site.com/map.html?region=2

And how do i then get that value into the snippet call?
Do snippets automatically look for values in a querystring?

Heres an example of fixed snippet call that i am using:
[!WebLoginPE? &type=`users` &usersList=`Members:default:default:surname:ASC:region(2)` !]
Its the region filter at the end i want to change dynamically

Thanks for any advice

Environment:
MODx 9.6.1
PHP 5.2
Apache 2
Linux Server

errr... did i write the problem clearly enough?
Still looking for help with this if anyone can spare a moment.

That’s odd I posted a reply and it’s gone.
Use this snippet to retrieve the query string info.

Call the snippet in place of your number 2

<?php
$region = $_GET['region'];
return $region;
?>

You should also give $region a standard number if there is no query or if the input is not a number

thanks guys - i’m still learning how flexible this system is... its great!
Im so used to NOT being able to manipulate a CMS, that its hard to break out of that mindset.
