Need help with PHP/MySQL error msg

[font=Courier New]Hi to All,

Thank you for looking into my error messages. [/font]
[font=Courier New]Could you please read the error messages and instruct as to what is happening and what I should do to resolve the issue?

[size=3]Situation -[/size]
[size=3]1) I have shopping cart instructions to create a new MySql db,(which I have done)[/size][/font]
[font=Courier New][size=3]
2) Then I was asked to [color=red]RUN[/color] the sql found in the database.sql to create the tables I’ll need for the shopping cart([color=red]which I wasn’t sure how to RUN this file after it was uploaded to the server[/color]). I clicked on the file in hopes that would work. I could not tell if it was successful or not. [color=royalblue]So, this maybe my first problem[/color].
[font=Courier New][size=3][/size][/font]
3) then, I was instructed to go to the cart’s admin panel and login
(this was successful). Then, to get started I needed to create
categories, so I clicked on “manage sites” and got these error msgs:
[/size]
//ERROR MSG FOUND AT THE TOP//
“Warning: mysql_fetch_array(): supplied argument is not a valid MySQL
result resource in /…/update/shopping_cart/categories.php on line 36”

//ERROR MSG FOUND AT THE BOTTOM//
“Warning: mysql_fetch_array(): supplied argument is not a valid MySQL
result resource in /…/update/shopping_cart/categories.php on line 91”

Again, thank you in advance for any help that someone may offer.[/font]

I am using a FREE Flash Shopping Cart. If you like, I found it here
I’m also attaching the README Files, if that helps.

If you need more info, pls let me know.
