How to have 'number of new PM's' using a style edit, *not* a template?

[Freestyler]

Ok, here's something I've been trying to achieve. I have a userbox (that's done through editing the style Header/Footer) that stays at the top of the browser (even when you scroll), and in the userbox I have the following data for the user:

User: username (which is done by using '$bbuserinfo[username]')
Posts: post count (done through '$bbuserinfo[posts]')

Those two both work fine, and display the correct values/info.

However, there's also underneath those two:

Local Time: users local time

and

You have number of new PM's new PM's.

But these two don't seem to want to work. Either I have the wrong variables (so if that's my only problem, please let me know what the variables are !), or there's some other method of displaying such info when editing styles and not templates?

Any help on the issue would be greatly appreciated, those two sets of info are driving me mad!
