get information from database

[error_22]

hi, im trying to learn how this works, but sadly i can't get it working. What am I doing wrong? The databse is called "test" and the only table i have is named "logo". There is one field in the logo table which also is named "logo"

PHP Code:

$server         = "localhost";
$db_name     = "dbname"
$user         = "user";
$pass           = "pass";

$logo="SELECT test * FROM logo";

$db_connection = 
mysql_connect("$server","$user","$pass") 
or die ("No DB Connection");
$db = mysql_select_db("$db_name",$db_connection) 
or die ("Couldn't select DB");

echo "$logo"; 


the "logo" field contains the URL to my logo. when running this i get a red cross. Can someone help an newbie?

Thanks in advance
Niklas
