Foruminfo variables and conditionals in header template?

[Pitman]

Is it still possible to use variables such as $foruminfo[title_clean] and $foruminfo[description] in conditional statements from the header template in 4.x? I've tried several different ways to try to get it to work, but so far have not had much luck.

The following doesn't seem to work from the header template:

<vb:if condition="$foruminfo['description']">{vb:raw foruminfo.description}</vb:if>

In 3.8.x I used:

<if condition="$foruminfo[title_clean]">

<if condition="$foruminfo[description]">

How would I go about recreating these conditional statements for the header template 4.x?

Any help would be extremely appreciated!

Thanks
