Take a step back, and:
my @data = \($response, $ofx_response);
print Dumper \...@data;
If you still get nothing, you'll have to move up further in the program
until you find out exactly where things are not being assigned to properly.
To get a better idea of what is happening live-time, put a line like the
following just before the variable assignments that appears to be broken:
$DB::single=2;
Then call your program like this:
% perl -d program
You'll be dropped into the debugger. Use 'w' to "watch" certain
variables for changes. Use 'c' to jump to the breakpoint we added into
the program code (via $DB::simple=2), and use 's' to "single step" each
line. Here is an example:
The problem:
Odd number of elements in hash assignment at tests/ref.pl line 8.
The program:
#!/usr/bin/perl
use warnings;
use strict;
print "...Start\n";
$DB::single = 2; # the debugger run the program up until this point
# if I hit 'c' once
my %hash = ( this => 'that', these => 'those', me => );
my @array = qw ( one two three );
my @data = \( %hash, @array);
__END__
% perl -d tests/ref.pl
# the line you see on the screen is the one to be executed NEXT
DB<1> w %hash
DB<2> c
main::(tests/ref.pl:10): my %hash = ( this => 'that', these =>
'those', me => );
DB<2> s # single step the %hash assignment
Odd number of elements in hash assignment at tests/ref.pl line 10.
at tests/ref.pl line 10
Watchpoint 0: %hash changed:
old value: ''
new value: 'these', 'those', 'me', '', 'this', 'that'
### ^^^
There is the empty assignment that is completely throwing off the hash.
In your case, you may have to move the breakpoint(s) around a bit, and
"watch" different variables until you sort out where the faulty
assignment is being attempted.
Hope this helps, even a little bit...
