mysql .inc file error

[303]

I apologize if this isn't the place to try and get help on this, as I am a fresh fish to these parts. But I am having this problem, see if you guys can make any sense.

The Code

$arr=mysql_fetch_array($raw_info);
$var="";
$var.=$arr['user_name'];
eval ("\$ifstatement=(\$$var);");
if ($statement=="on")

The Error
T_VARIABLE' or `'$'' in /home/nick/wwwforum/inc/sql/sql_delete_
users.inc(62) :
eval()'d code on line 1

Make any sense? thanks alot.

$arr=mysql_fetch_array($raw_info); 
$var=$arr['username'];
$ifstatement=$var;
