bfc_download_cat_bit is the template. You create it by calling the vB_Template:create method, and then you need to register every variable you want to use inside that template, no matter what's saved inside that variable. It can contain a rendered template, or it can contain just a simple boolean false or true. That does not matter, you need to register it to be able to use it. Then, in the next step, you render the template.
