    The values containing spaces must be escaped, otherwise the parsing will not
    work. Please do now forget to use the issue/article preview function: this
    will display syntax errors so you *will know* why it doesn't work.

    Please see this page, at the bottom:
    http://code.campware.org/manuals/campsite/3.2/index.php?id=63

    Spaces in values must be escaped with backslash.

    E.g.: constraints="topic is Global\ Warming:en"
    In this case "Global Warming" is the topic name.

    I understand the escaping of spaces, but if I send a topic as a parameter, and create a variabe {{ $var }}, how can I test to see if $var contains a space and automatically espace the spaces?

    When I display an article, I provide a link which says "More in My Topic". Click the link and it sends a parameter ...?My+Topic. Since the link is computer generated, I do not know in advance whether it contains a space.

    Ahhh, I just found the "replace" modifier. I think I can make that work.

    Alright, I know when I'm defeated. I could use a little help with syntax. Again, the scenario is:

    1) I pass a parameter which contains the topic I wish to be displayed.
    2) I grab the parameter and escape any spaces if there are any.
    3) Insert that parameter within list_articles.

    Here is what my thinking is, but I know the syntax is wrong:

    {{ assign var=cat value=`$smarty.get.category` }}
    {{ assign var=cat_clean value=`$smarty.get.category` }}
    {{ if $cat != '' }}
    {{ set_topic name="`$cat_topic|replace:' ':'\ '`:en" }}
    {{ $cat_clean }}

    {{ /if }}
    {{ list_articles length="20" constraints='OnSection is On' order='byPublishDate desc' }}

    ...

    Alright, I'm slowly getting the hang of syntax ... despite the gray hair it is causing!

    For anyone following in my footsteps, this works:

    {{ assign var=cat value=`$smarty.get.category` }}
    {{ assign var=cat_clean value=`$smarty.get.category` }}
    {{ if $cat != '' }}
    {{ assign var=cat value=$cat|replace:' ':'\ ' }}
    {{ set_topic name="`$cat`:`$campsite->language->code`" }}
    {{ $cat_clean }}

    {{ /if }}
