Using conditions?

[DislexiK]

Good day,

I am currently trying to integrate the mod_rewrite hack with the Geek Article System but I am having a problem with a little something. Basically there is a condition set in functions_geekarticles:

$GAS_is_article=in_array($thread['forumid'],$GAS_forums);

This checks to see if the forum ID that the thread is in is one of the forum IDs that is apart of the GASystem. Now I need to be able to use a condition like:

<if condition="$GAS_is_article"> Do something <else /> Do something else </if>

The problem is I cannot seem to use this condition in the "pagenav_pagelink" template, how would I go about making this possible?

Thanks in advance.

No one able to help?
