I think I experinced your problem, so try my remedy :
1st define a variable ase name of your checkbox
2nd assign what else that pulled out ... to that varialbe, thus you have a check box which has different name depending on what the user chooses.
like this:

$query = select * from ... ;
$result = mysql_query( $query, "sqlLink" );
$getResult = mysql_fetch_array( $result );

name = $getResult["..."];

I hope it helps to you
