as on my last post, I started creating a site w/hostgator.
I found out that they don't support fantastico, and in order for me to install it directly on my site, I need some type of script knoweldge.
I have absolutely no html knowledge.....I want a simple click & add type of slide show gallery on my site.
What are my options? Are there any other gallery options that I have where I can just somehow add it to my site in an easy way?

Most scripts come with some fairly simple instructions, but it isn't as simple as point and click. Your choices are to move to someone that supports Fantastico (there are also other one-click installers like Installatron), ask your host for help, hire someone to help (and have them explain it to you so you can update later), or dig into the installation docs and learn how to do it yourself.
In the end, learning how yourself is the best way, since then you could update or even change apps yourself. If you get stuck, ask here about the issue and someone will no doubt be able to assist you.
Good luck!

HostGator does support Fantastico Deluxe! I've double checked in my control panel to be sure, but there it was!

They definitely do and for a photo gallery check out 4Images Gallery and Coppermine Photo Gallery.

Am I getting the run around from them?
One tech says it can't be installed on sitebuilder, then another replies with: "you need a link in sitebuilder to link to your fantastico script install"

Maybe what the HG tech meant is that you could not integrate the functions of your sitebuilder with the script (gallery) installed via fantastico. You would need some manual tweaking in order to accomplish what you need.
