I'm looking for a free and simple script that lets the user rate something with 1-5 and then it shows how many people have rated and the average score. been to hotscripts.com no luck.

The first one has the option you are looking for!

I want it free.that's just 30 day trial

There should be something like this built into another script such as a photogallery or portal. If there's something specific you're rating, you may check into a script for that instead of just the rating piece of the script.
