I see this is an old thread. I figured I would search before starting a new one, however, this doesn't really answer the question.

I don't want to change the display order as they appear on the memberslist, I want the users to be able to click the Custom Category Field (as a link), and have it sort ASC, DESC - just like the username Category field.

Explaination
In the template:
memberlist
There is a line that sets the username as a sortable category.

<td class="thead" align="$stylevar[left]" nowrap="nowrap"><a href="$sorturl&amp;order=ASC&amp;sort=username&amp;pp=$perpage$usergrouplink">$vbphrase[username]</a> $sortarrow[username]</td>

Now since the memberlist_results_header handles the custom fields you find in the template:
memberlist_results_header
Default:

<td class="thead" nowrap="nowrap">$customfield</td>

Modified:

<td class="thead" nowrap="nowrap">
<a href="$sorturl&amp;order=ASC&amp;sort=$customfield&amp;pp=$perpage$usergrouplink">$customfield</a>
$sortarrow[customfield]
</td>

Now that spits out a link looking like:

http://blah/blah/forums/memberlist.php?&order=ASC&sort=Location&pp=30

It obviously doesn't like the sort=Location (Location being the $customfield).

Is there anyway to do this easily without writing new code into the memberslist.php? and if not, a little help on the code would be great.
