If I put the following command in a page it works fine:
[code]{CGUserDirectory group="Producers" summarytemplate="Summary_Farm_Gate"
prop="availability" propval="Farm Gate"}[/code]

BUT... Farm Gate is in a multiple select list so only Producers with a single
selection "Farm Gate" are returned (approx 8 from 21 known entries)

When I change the code to:
[code]{CGUserDirectory group="Producers" summarytemplate="Summary_Farm_Gate"
prop="availability" uselike="1" propval="Farm Gate%"}[/code]

A summary of all 21 users are found but the link to an individual producer's
details no longer works.
I receive the following error:
[quote]Error 406 Not Acceptable
An appropriate representation of the requested resource /index.php could not be
found on this server.
Additionally, a 404 Not Found error was encountered while trying to use an
ErrorDocument to handle the request.[/quote]

An example of the URL created for the "detail" link is:

index.php?mact=CGUserDirectory,cntnt01,detail,0&cntnt01group=Producers&cntnt01summarytemplate=Summary_Farm_Gate&cntnt01prop=availability&cntnt01uselike=1&cntnt01propval=Farm
Gate%25&cntnt01uid=58&cntnt01returnid=109

The URL is created by the following code in the summary template:
[code]<a href="{$oneuser.detail_url}"
title="{$onepropvalue}">{$onepropvalue}</a>[/code]

Something is very wrong here.
