Add Sales Rep (Issuer First Name) To Invoice.tpl

Hi, I am trying to add the sales rep to each invoice. Version 4.3.

I modified the invoice.tpl in the design\backend\mail\templates\orders folder to add:

{__("sales_rep")}:
{$user_data.firstname}
which works but it is not pulling the issuer information from the database. I am guessing I need some more code or need to add something like this
{include file="views/order_management/components/issuer_info.tpl" user_data=$order_info.issuer_data}
to the template, but not sure where to add it. Anyone familiar with this?

Please make sure that the issuer_data array is not empty using the following code

{$order_info.issuer_data|fn_print_r}

Please make sure that the issuer_data array is not empty using the following code

{$order_info.issuer_data|fn_print_r}

Returns the following data for an order I was testing on. So the data is there.

Array
(
[user_id] => 3922
[user_login] => user_3922
[company_id] => 1
[firstname] => Harry
[lastname] => Belechto
[email] => harry@dark-storm.com
[user_type] => A
)


I also tried {$issuer_data.firstname} but that did not work.

Got it to work. Used {$order_info.issuer_data.firstname}
