Warning: mysql_fetch_assoc() expects parameter 1 to be resource, null given

Hi all,

I need help with this error that always appers when I add a dynamic table to my search results page. The search DOES produce the correct results, strangely. I search the database by name.

Dreamweaver cs3, xampp, PHP, mySQL     install dir: C:\xampp\htdocs

The strange thing is that results actually get produced so it DOES work but, this error keeps getting thrown and i have to remove that line from my code to get rid of the error, but then i get a red exclamtion point on the repeat region server behavour and i want to solve this...

my server behavour is listed like this  ! Repeat Region (@@RecordsetName@@) 

line 47, the error line is in red below
