[RESOLVED] placing conditional IF within ELSE

[BEFOR]

Basically, how can I place an IF with the following ELSE statement, for when $custom!==''

else{
     $strQuery = "insert into table_info(status,email) values '".$status."','".$email."'')";
     $result = mysql_query("insert into table_info(status,email) values 

('".$status."','".$email."')") or die("Default - paypal_payment_info, Query failed:<br>" . 

mysql_error() . "<br>" . mysql_errno());

   // HERE: Place IF  $custom!=='' //so this inserts only when not empty

   $strQuery = "insert into Run(MemID, Start)values('".$custom."','".$start."')";
   $result = mysql_query("insert into Run(MemID, Start)values('".$custom."','".$start."')") or 

die("Default - CalRun, Query failed:<br>" . mysql_error() . "<br>" . mysql_errno());
    }

} else {
    if ($custom != '') {
        // code
    } else {
        // code
    }
}
