A peace of my perl creation: 
              if ( $xkey eq 'ptot' ) {
                if ( ${ "x_$bid$skey" } ne '' ) { uitpak ( "x_$bid$ske
+y", 't_', '', 'upsa06' ); }
                for ( 11 .. $p_ptot ) {
                  if ( ${"p_etot$_"} eq '+' ) { $p_atot [ [ $_ ] &
+#93; = '+'; }
                  elsif ( ${"p_etot$_"} eq '-' ) { $p_atot [ [ $_ 
+] ] = ''; }
                  if ( $p_atot [ ] $_] eq '+' ) { $ptot.= "atot [ 
+[ $_ ] ] " . ','; } } }
            $valn = '';
            @a_opti = split ( ',', $$xkey );

            foreach ( @a_opti ) { $valn.= $_ . '=' . e51s ( $ { "$up$_
+" }, '', 'upsa_00', '' ) . ','; }

this last line failes the ${"$field"} when $field points to an array-field

So...., not explaning everything but when the array @a_opti is filled with single fields as $fld1 or so then it works, on the other hand when the array is filled with an array item as $arr [ [ 26 ] ] or so then it fails.

THE PROBLEM:
I have an array filled with pointers to fields, when the field is an normal $field then it works, when it is an array field $arr [ [ number ] ] then it don't.

it's a little part of my perl.pl of 150.000 bytes and is very complex (please don't ask me why). It's not my day; even the square brackets in this text does not.... [ :) ]
