How to merge two catalog items flow into one in Flow desginer

[test3445]

 Hello I have a need which is to merge two catalog items into a single one and I have 2 scripts (workflows) that I want to merge into a single one as well. 

Problem is I a want to display the action (add,modify,delete) inside the descritipion of the change request  created but it doesnt display it in the description :

Change request description field:

 

My expected result :

and here is the script I used in flow designer  and I want to combine into one script that will display both add and delete action inside the description : 

  var aliasArr = fd_data._1__get_catalog_variables.liste_d_alias_dns_ajouter;

           var description = "Comments:  " + fd_data._1__get_catalog_variables.comments + "\n"+

        "List of DNS aliases:  " + "\n";

    var j = 0 ;

    for (var i = 0; i < aliasArr.length; i++) {

    j = i + 1;

        description += "Name["+j+"]:  " + aliasArr[i].name + "\n" +

            "Domain["+j+"]:  " + aliasArr[i].domain + "\n" +

            "Name or IP address["+j+"]:  " + aliasArr[i].name_or_ip_address  + "\n\n"

    }

    return description;

var aliasArr = fd_data._1__get_catalog_variables.list_of_dns_delete;

var description = "Comments:  " + fd_data._1__get_catalog_variables.comments + "\n"+

    "List of DNS aliases:  " + "\n";

var j = 0 ;

for (var i = 0; i < aliasArr.length; i++) {

    j = i + 1;

    description += "Name["+j+"]:  " + aliasArr[i].name_remove + "\n" +

        "Domain["+j+"]:  " + aliasArr[i].domain_remove + "\n" +

        "Name or IP address["+j+"]:  " + aliasArr[i].name_or_ip_address_remove  + "\n\n"

}

return description;

Any help will be much appreciated.

All good I misspelled a variable but now when using your script the change request is no longer created.
