Can someone please assist?

It seems like you are using a very recent version of OpenCart. The data attribute is no longer a member of the Controller class, as you can see in the version history.
I also assume you are using a third-party extension from the Shop. Searching for "stanbic" brings up one result, which isn't compatible with any recent OpenCart version.
Try the same extension on an older OpenCart version. Or you can try to fix the implementation yourself:
Create a local variable $data = array(); right at the beginning of the index function
Replace all references to "$this->data" with "$data"
Pass the local $data to the setOutput function: $this->response->setOutput($this->load->view('foldername/filename.tpl',
$data));
This isnt tested and it is likely that you will have to modify more code, because it appears that the OpenCart 2.x code is quite different from the 1.5.x codebase. Use a recent controller as reference.
