Need help w/file naming please!

[yeauh]

Hi,
I'm trying to link my sub-pages on
http://worstclothing.com/
with link written like this:
a href="index.php?location=aboutus"
but there's not actually an "aboutus.php" file, only global.php, header.php, and footer.php. How can I find how how to give correct file names to the new sub-pages I've made so that they will work with the above link format? I don't know where these files are being stored or how they're being called up. I'd appreciate any input...

How did you create the aboutus page? Sounds like you are using a CMS and the pages are stored in a database. In any case, we can't help you without seeing the code, or at least knowing what CMS you are using.
