Hi I'd like to get the names of all the macros in a pt and of all the slots within each macro, but I'm getting guarded_item errors. In PageTemplate.py, I have found pt_macros(), which returns a dictionary with macro names as keys. Great so far. I can even print pt_macros() and get a string representing the whole dictionary. However, when I try to access the corresponding value so I can look for the slots inside each macro, I get the error shown below. Is there a way of gettting the macros and their slots from a script, or do I have to write an external method / product? Thanks Felix.
