What template is this? (pic inside) And... how can I make it say this: (code inside)

[Protonus]

Ok, i *THINK* this part that I circled in red is the NAVBAR template... but I'm not sure since I can't make it do what I want....
so first off, is this the NAVBAR template (circled in red)?

This area in question is the top of my forum list.

Secondly, if it IS, I'm trying to add something to the display after where it has the total members. This is the code I'm changing:

<div><img src="$stylevar[imgdir_misc]/arrow.gif" alt="" class="inlineimg" /> $vbphrase[threads]: $totalthreads, $vbphrase[posts]: $totalposts, $vbphrase[members]: $numbermembers<if condition="$show['activemembers']">,

All I want to add is the average member age, based off this plugin. I have it installed so I would htink it would be a universal variable? This is the plugin:

I added 'Average Age: $avg_age' after the end of the above code so it looks like this:

<div><img src="$stylevar[imgdir_misc]/arrow.gif" alt="" class="inlineimg" /> $vbphrase[threads]: $totalthreads, $vbphrase[posts]: $totalposts, $vbphrase[members]: $numbermembers<if condition="$show['activemembers']">, Average Age: $avg_age,

but it seems to have no effect on it at all, hence why I'm wondering if I have the right template...

Thanks guys!
