[Zope] NEWBIE: manage_delObject, Thanks!!

[Michael]

Hi Danny,

I worked on this until 12:30 last night and finally got it to work!  Thanks 
so much for the explanation, I looked everywhere and couldn't find much 
documentation on this.  I was calling my "delete" a little differently than 
what you described, which is why it took a while to get it working, but I 
couldn't have done it without your help.  You did a great job of explaining 
the concept.  Thanks again.

Michael
