One script changes the default database

[Trana]

I recently added phpadsnew to my header to display a banner ad on every page. As a result of adding this script, my shoutbox module stopped working.

The problem seems to be that after the banner ad script executes, it leaves the default database as "bannerads" instead of "forum" (my VBB default).

I'm fairly new to VBB/PHP, so this may seem like an easy question, but how can I do a "USE FORUM" SQL command just after the banner ads script executes?

Any help would be appreciated.
