[Zope] Boolean

[Jason Spisak]

Zopsters:

After reading again for a boolean info the DTML docs, I can't seem to
see the best route to test in DTML.  
I tried a simple <!--#if "foo is true"-->, didn't work

I thought, since bolean deal with 1 and 0, I'd use 
<!--#if "foo==1"--> for true and 
<!--#if "foo==0"--> for false.  That didn't work either.

If I however used blank or '' as the search criteria it worked, as in
<!--#if "foo==''"--> for true, and nothing for false.

Whats going on with boolean, and can somebody point in the right
direction?

All the best,
