PLEASE IGNORE MY POST SENT MOMENTS AGO. I WAS NOT FINISHED TYPING.

I have the following post that gets a user's selection from a 
page then looks up the corresponding records for the selection and

put them into a hash refrence. THat part works fine. How can I then call another page/route

with that hash_refrence?

For example;

 post '/mypage' => sub { # let user make a selection
    
    my $select_id = params->{Sselect};
    
    print "\n\nLooks Like They Selected No: $select_id\n\n";

    # look up DB records corresponding to $select_id;

    # store them in hash refrence $sel_ref

}
  

 Now I would like to call template/page sport_add but I would like it to have $sel_ref so 

 that it could put that data into the template sport_add

get '/sport_add' => sub {

   template 'sport_add.tt', {    
      'MyTypes' => $sel_ref,  #
      'Testing'   => "This is text to test to make sure this will come through", 
      # to test, use this like <% Testing %> on your template page

}, {};

};
 

  
    
Thanks for any help. Have a great afternoon.
