FAQ 233

A user pointed out an error in FAQ 233, which refers to %%head%% as a variable, when in fact it's a property. I think it would be nice to correct the terminology.

In addition, this FAQ only relevant to custom styles, not overrides; you can't override LASTN_PAGE (or anything_PAGE) which is where the property %%head%% must be. So I think that the first sentence shouldn't refer to overrides at all.
