i have a

workiing script shows below(the first sub below)

. basically it handling strings passed in subroutine and make a loop which shows below. ( it is working sciprt) the string passed in is an array or sting. {name => 'name222',colour => 'yellow'} or {name => 'name222',colour => 'yellow'},{name => 'name333',colour => 'yellow333'} 

sub { ### this sub works well.

# splits them up into stuff like "{name => 'name222',colour => 'yellow
+'}" 
my @split = (split /\Q},{/, $_[0]); 

my @loop; 
foreach (@split) { 
s/^{//; 
s/}$//; 
my $hash; 
my $hash1; 
my @tmp = split /,/, $_; # now lets split them at ', 

my @subloop; 

foreach my $tmp (@tmp) { 
my $hash; 
my ($name,$value) = split / => /, $tmp; 

$hash->{name} = $name; 
$hash->{value} = $value; 
$hash->{value} =~ s/^\'//; 
$hash->{value} =~ s/\'$//; 
push @subloop, $hash; 

} 
#$hash1->{name} = "subtotal"; 
#$hash1->{value} = "999"; 
#push(@subloop, $hash1); 

push @loop, { subloop => \@subloop }; 
} 

return { split_loop => \@loop }; 

}

since its output is not so easy to be formated into a desired layout.

i try to rewrite it based on first subroutine's concpets.

here is my one. but it doese not work. i suspect it is not passed the scalar value properly to the sub or it is not split it well as when i replace it with directly. it produce a result as i expected. I have already stuck on this issue for long time . could any senoir could solve the problem or light me up for this problem? 
 

sub { 


my ($cgi, $session,$product,$tags,$itemmaxtemp,$itemID, $incomingdata)
+;

#my @incomingdata = @_ ;
#my @incomingdata = $_[0];
#my @incomingdata = (@_);
#my @incomingdata = $_;    
my $incomingdata =  split /\Q},{/, $_[0];

# i have tried all above possibility and all failed.
# have been returned a blank page.
# when i filling @partofcookie directly with
#({name => 'ddd111',quantity => 11,price => '11',colour => '11red',size => '11xxl',itemID => '1111tiem'},{quantity => '2',name => '222gmailoknow',price => '228',itemID => '222item'});
# it works well. while once i replace
#@partofcookie with the value of @incomingdata , i will be
return a blank screen. whywhy?
 

my  @partofcookie= ({name => 'ddd111',quantity => 11,price => '11',col
+our => '11red',size => '11xxl',itemID => '1111tiem'},{quantity => '2'
+,name => '222gmailoknow',price => '228',itemID => '222item'});
foreach my $product ( @partofcookie ) {      #####

$product->{prod_subtotal} = $product->{price} * $product->{quantity}; 
$tags->{total_price} += $product->{prod_subtotal}; 
$tags->{itemmaxtemp}=$itemmaxtemp;
$tags->{itemID}=$itemID;

push @{$tags->{cart_loop}}, $product; 
} 
my @xxx;
@xxx = @{$tags->{cart_loop}};
  return { orderdetail_loop => \@xxx};
  }
