mySql Query **SOLVED**

[Sgt-Peppa]

Hey all, it been a while since my last php project, and I guess I frogot everything........

I am trying to get a result from db in mySql. But i always get this error Message:

Warning: Supplied argument is not a valid MySQL result resource in ...

Heres the relevant code:

$queryTeams = "SELECT * FROM teams WHERE Group = 'A'";
$resultTeams = mysql_query($queryTeams);
while($Team = mysql_fetch_array($resultTeams)) // this is where the error is pointing 

Thanks
