Custom Record as list in HTML/PDF Template
We've created a new record with a sublist with information that we need to display in the related HTML/PDF Template.
I have a lot of examples how to use the #list option but I have no idea what 'ID' I need to use.
I just tried 'Custom':
Because on the record the information is under the 'tab - Custom'. Unfortunately no result.
I also tried the label of the saved search on the Custom Record Type:
Even with this 'label' I don't get results, and i'm sure that there is information dat must be shown.
Can someone point me in the right direction to solve this?
