Need advice about external PHP poll script

[stark427]

Hello there

I'm constructing a main page for my site...
I want to include a php poll. I have found a script which seems that gives a devent result :

http://cerebuswebmaster.com/onsite/free_php_scripts/

In the instructions it says that I need to run a database.sql query, which comes with the downloaded packet.

I hesitate to run this query cause I don't have any idea what effects this will have at my database. (the database I have for my VB).

Anyone who could give me any ideas on whether it could mess my vb database or not?
I mean is it safe to run such query? Can I revert the database to what it was before - if this query causes any problems?

I would appreciate any feedback on this.
thanx
