Please help! Issues with jQuery Conflict

Hi, I recently converted an HTML site to WordPress and I am having an issues with a jQuery conflict.

The site has a drop down search function in the navigation, and it also has the Search and Filter Pro plugin installed for searching posts / pages.

If the drop down search is active (not commented out), the Search and Filter plugin does not dynamically filter the results once a selection is made. If I comment out the drop down search, the Search and Filter plugin works (showing dynamic results like it should)

I found out I am having a jQuery conflict.

I did some research, and a lot of people say to use the noConflict function in the PHP. I am just not sure where / how to implement this.

So I have 2 questions:

1. How do I implement the noConflict code?

2. Is there any other option so that I can have more than 1 instance of jQuery on my site?

Thanks!
