Question on "return"

I have a very strange problem.

Based on Ben`s artikel i am building up a small comunty system.
After i did the admin stuff, i wanted to let the users change there own
detailpage.
The idea ist simple:
IF User ist logged in AND pageuserid=userid
a link is been placed to a edit page(which ist secured too ;-) ).

Similar to the admin query i did this:

//-----------------------------------------------------------
function UseridIsDetailId()
{


session_start();

// Check that the session id is valid
$dbVars = new dbVars();

@$svrConn = mysql_connect($dbVars->strServer, $dbVars->strUser, $dbVars->strPass);

if($svrConn)
{
$dbConn = mysql_select_db($dbVars->strDb, $svrConn);

if($dbConn)
{
$strQuery = "SELECT {$this->__FieldNameSess}, {$this->__FieldNameSec}, {$this->__FieldNameUserId} FROM {$this->__StoreSessionTableName} ";
$strQuery .= "WHERE {$this->__FieldNameSess} = '" . session_id() . "' AND {$this->__FieldNameUserId} = '$userid'" ;


$results = @mysql_query($strQuery);

if($result = @mysql_fetch_array($results))
{ return $result{$this->__FieldNameSec}; }
else
{ return 0; }
}
else
{ return false; }
}
else
{ return false; }

}

//________________________________________________
Debuggin the Query gets this:
Array ( [0] => 0082810f7a81847def0077ec0a55d0eb
[sessionid] => 0082810f7a81847def0077ec0a55d0eb
[1] => 1
[auth] => 1
[2] => 27
[userid] => 27 )
//___________________________________________

So als {$this->__FieldNameSec} = auth the funktion should return "1" and i would be happy.
But NO!!


the problem has du be somewere here if($result = @mysql_fetch_array($results))
{ return $result{$this->__FieldNameSec}; }
else
{ return 0; }

//___________________________________________

if i change { return $result{$this->__FieldNameSec}; }
else
{ return 1; }//<-----to that it works, so were is the mistake here:{ return $result{$this->__FieldNameSec}; }

I am workin 2 days on that problem help would be very kind.

Thank you very much

Are you receiving any error messages at all?

Also, where is "$userid" coming from? Is it entered by the user on a form?

As i didnt find the mistake, ich wrote the funktion on to the page, that worked. So the mistake was calling and debugging a class funktion not in the class.php.

The Userid comes from the funktion that lists all related data to the current userid. Perhaps it could work if i could make that var global, but i dont know how. Anyway its works ok now.
Perhaps i should have dont somethink like $GET['userid'] ...
