Filter pdf for category

Good afternoon, I hope you are very well!
I want to be able to generate a pdf file of my products but with a filter by category and I can’t do it, when I don’t use AND and leave, True, everything works fine.
I have 1 template called Inventory, with the following data:
Name- stock- category - price and several other things.
To create the pdfs separately, create a template called Catalogs with the following Data:

CatalogID -Type- Date -Categories- File- Update

This is my code that does not work:

<< Start: FILTER (“Inventory”, AND ([Category] = [Categories]))) >>
<<In Stock>>


What am I doing wrong?

You’re using AND() improperly.
