OK here goes...
A. if ($initiative = 'on') assigns variable and returns true it does not evaluate try  if ($initiative eq 'on')
B. What are the checkboxes returning? would s/\W//g be more effective stripping non word charecters?
C. If you are using checkboxes rather than radio boxes then multiple ones can be checked.
my $hash ={ Initiative=>'DriveInitiative', 
            ResOrientation => 'DriveResOrient'};
     
my @clauses = ();
foreach my $checkbox (keys %$hash) {
   push @clauses, $hash->{$checkbox} if validate($cgi->param($checkbox
+));
}

my $where_clause = join(' and ',map($_.'= 'on', @clauses));

my $sql = "select a.ResType, a.ResLevel, a.ResManage 
                  a.Details, a.Length, a.Source, a.Cost, a.FurtherDeta
+ils 
             from Resources a 
            INNER JOIN ResourceSettings b ON a.ResID = b.ResID"; 
$sql .= " where $where_clause " if ($where_clause);
$sql .= " order by a.ResType, a.ResLevel, a.ResManage, 
                a.Details, a.Length, a.Source, a.Cost, a.FurtherDetail
+s";
