PDF Maker - Modules related to related modules

Hi All,

I'm trying to make a pdf that contains information from multiple modules.

I'm able to get the information from the first layer of related modules but not the second or third layers.

In the reports module it is possible for me to get to all to information that I need and put it into a report but I need to try and get the same function in the pdf maker.

I can't help but feel like I'm missing something easy. If anyone has any ideas it would be appreciated.

Let me give you an example I'm trying to get a pet patient history pdf, to get this PDF i need to get the
clients details,
the pet's details,
the consultation
and procedure details,
the prescription details and
the medication details

all on one pdf.

Thanks
Vincent
