I am working on a classified Ads module. I am having issues making some data available to the header_template and footer template. When I place a {debug output="html"} in the header_template I don't see any of the information I have available in the row_template. I assume that this has to do with the custom ranking script. How can I make the information available to the row_template as well as the header template? Any advice would be greatly appreciated.

What info do you need to make available in the header? Info from the rows cannot be available in the ranking header and footer, but you can pass in additional info using the replace parameter.
If the "replace" parameter is given as an array (this must be prepared beforehand with the {jr_array} template function), then Jamroom will make the replace values available as template variables - i.e. {$REPLACE_0}, {$REPLACE_1}, etc.

Thanks for the reply SteveX. Im not sure the documentation is specific enough for me to understand its usage. Would you be able to give me an example of its usage? How would I determine which value would be assigned to $REPLACE_1, $REPLACE_2, etc?

Thanks again for the reply steveX. How would I apply your example to the retrieval of data from the database from a custom ranking script or from the querystring? IE: ad_title from the DB or order from the querystring?

Whenver you are using the ranking system, the "common" variables will be available in all templates - i.e. $RANK_ORDER will contain the order as passed in. If "ad_title" is a column in the database, and you select it in your ranking plugin, then it will become $AD_TITLE in your row_template as well.

Thanks for the reply, guys. Heres what Im trying to accomplish. When the ranking script is called, it gathers information from the database, depending on what it is given(pretty typical of a ranking script) If the ranking script isn't given a category_id or an ad_id, It will retrieve a list of Ad categories for display. When the user clicks on one of the categories, it calls the ranking script again, but this time with a category_ID. Since the ranking script received a category_ID but not an ad_id, It retrieves a list of ads, within the category_id it was given.
During this process, I want to have the category Title and description, displayed via the template_header. Then let the row_template, output the list of ad titles(as links that give the ranking script the category_id and its ad_id)
If I try to display the category name and description within the row_template, I imagine it would be outputted as many times as the row_template is "looped" through. So I need to be able to give the header_template the category_name and category_description, if it is needs to be displayed.
Any Ideas? Thanks again for all your help guys. The Jamroom staff and members rock!!! A+

If you make the category title and description available in every ranking row, you can use a jr_unique_block at the top of the template to only output it once on the first loop:
