[Zope] Dynamic Sum

[Charlie Reiman]

I would create a brain (see the Zope book) to compute cost * qty as a new
field, then use the dtml total var on that synthetic field.

BTW, your corp mandated sig is a little bit out of control. There was a day
when sigs of more than 4 lines brought forth a firestorm of criticism.

I miss those days.
