[Zope] Re: squirting variable definitions into macros using fill-slot

[Edward Muller]

I'm a moron!

I've been wondering how to pass variables to macros for a month now!

multiple times (state select boxes for instance) ... 

It just never dawned on me to combine the two!

Whack! Whack! Whack!

Arg!
