heh. While i have edited some things in the catalog, i've saved the cart
page for the last day or two, precisely because i'm not familiar with the
way Interchange processes forms. I've stuck to the simple parts, and
usually danced around Interchange and used plain CGI between the pages i
I diff'ed the cart component with the foundation cart and the one from the
tarball (i knew keeping around would come in handy :)) and found something
the catalog's cart, aside from the edits i made (all of which i remember),
appears to have changed quite a bit from the foundation's cart. What's
strange is that a couple of the tags appear to have been parsed. Not all of
them; no, that could be easily chalked up to some nitwit 'view source'ing a
catalog's cart and copying it over. Only certain tags have been replaced.
The [modifier-name foo], [quantity-name], and [list]bar[/list] tags appear
to have been expanded (to foo0, quantity0, and a bunch of bars,
respectively). Replacing these tags, and deleting the fluff that resulted
from parsing them, appears to have fixed the problem.
I have to wonder how it happened, though. This doesn't really look like
anything people would be boneheaded enough to do, especially since the only
other person working on this site hasn't touched the cart pages, and is
brighter than that anyway... :)
