Showing associated Table info with Inner Join on manage.php as a td - Trongate MX

Okay I am new to PHP, but can figure most of it out. I have 3 Tables
Table one = 'branches' with columns: id, name, url_string, abbreviation, website, branch_types_id, branch_statuses_id
Table two = 'branch_types' with columns: id, url_string, type
Table three = 'branch_statuses' with columns: id, url_string, name

I am trying to get the branch_types(name) to show up in the manage.php table for module Branches that is associated with the branches(branch_types_id) instead of just the int that is stored for each record in 'branch_types_id'. and 'branch_statues_id' respectively

I have created a module relation for both to branches

I have it where it does show on my create.php as dropdowns to create the relationship and select the respective id to branch_statuses_id and branch_types_id.

I have tried creating a function in branches.php controller

I have tried using the $this->module('module_relations) string, I have even tried

I have looked at this for too long I bet it is a simple fix I am just missing it

Here is my manage.php

but I am getting Fatal error: Uncaught Error: Using $this when not in object context
any help will be apricated.

Dan, Thank you for your direction I had not turned that on. I fixed my issue by adding the following to my Branches.php Controller file under the manage function

and then this to my manage.php file

Thanks for the debug idea
