I have two Array of Hashes: The first contains values for a current time interval and the second contains values for a previous time interval.

@AoHcurrent=(
 
    {
       node  => "ABC",
       link     => "DEF",
       time     => "10:00",
       value      => "100",
    },
    {
       node  => "FGH",
       link     => "IJK",
       time     => "10:00",
       value      => "200",
    },
  );

AoHprevious=
   (
    {
       node  => "ABC",
       link     => "DEF",
       time     => "09:45",
       value      => "10",
    },
    {
       node  => "FGH",
       link     => "IJK",
       time     => "09:45",
       value      => "50",
    },
  );

I want to now use HTML-Template to present this data. Something like :

NODE LINK VALUE
---------------------
ABC  DEF  100(10)
FGH  IJK  200 (50)
[download]

the values in brackets represent the previous value.

my %html_template_parameters =    (
AOHCURRENT  => \@AoHcurrent,
AOHPREVIOUS => \@AoHprevious,
);
                         
    my $html_template=qq{Report.tmpl};
    my $html_output=qq{Report.html};
    htmlReport($html_template,$html_output,\%html_template_parameters)
+;
[download]

where htmlReport is a function that generates the report

I require guidance on defining the Report.tmpl file.

Thanks you in advance
