Hello all Monks

I've got a strange problem .. inside a sub I've declared a variable as my with three possible values ..

1. 'limit $nmbr1,$nmbr2'

2. 'limit $nmbr2'

3. not defined/false/null .. whatever ..

Here is the code. 

sub get_all_artid_from_kategoriid
{
    my ($self) = shift;
    my (%params) = @_;
    my $LIMIT     = 'limit ' . $params{'limitantal'} if (($params{'lim
+itantal'}) && (!$params{'limitstart'}));
    $LIMIT        = 'limit ' . $params{'limitstart'} . "," . $params{'
+limitantal'} if (($params{'limitantal'}) && ($params{'limitstart'}));
    my $ORDNING = " order by $params{'order'} " if ($params{'order'});
    my $GROUP    = " group by $params{'groupby'} " if ($params{'groupb
+y'});
    print STDERR "LIMIT = $LIMIT || limitantal = $params{'limitantal'}
+\n";
.
some other code.....
.
}

The problem is that if I call the sub without the values 'limitstart' and 'limitantal' the STDERR row prints out 

LIMIT = limit 20,20 || limitantal =

NOW comes the strange part ,, atleast for me....

If I change the code like this. 

.
.
    my $LIMIT;
    $LIMIT     = 'limit ' . $params{'limitantal'} if (($params{'limita
+ntal'}) && (!$params{'limitstart'}));
    $LIMIT        = 'limit ' . $params{'limitstart'} . "," . $params{'
+limitantal'} if (($params{'limitantal'}) && ($params{'limitstart'}));
.
.

Then the STDERR row prints out the following. 

LIMIT =  || limitantal =

Which I think the first code-example would do too..

Any ideas?? Am I still to tired? .. (GMT+1 = 11.34am)

Best regards
