Mysql & Select Question -- Help needed

Hello World, I have a search page that has a select on it and I would like to have the value with $age selected on it. I don't know how to do this, though. I tried this, but it doesn't work. Please tell me what I did wrong. Thank you so much everybody! :-) if ($row_age = @mysql_fetch_array ($result_age)) { do { $select_age .= "\t<option value=\"{$row_age["age_ix"]}\""; if ($age == "{$row_age["age_ix"]}") { echo " selected"; } // Problem Line? $select_age .= ">{$row_age["age"]}\n"; } while($row_age = @mysql_fetch_array($result_age)); } P.S. Does anyone know of the differences between SQL 7 and mysql? That would be very helpful. Thanks again!
