This is the same problem as last time. You must CALL the Date method, not
just reference it. The above line should read:

  <dtml-call "REQUEST.set('CurrentDate', ZopeTime().Date()">

Note the use of parens on Date().

Try it for yourself by putting the following in a DTML Method:

  <dtml-var expr="ZopeTime().Date">

You get:
  
  <method DateTime.Date of DateTime instance at 568eb0>

if you do a View | Source in your browser.

It does, if you CALL it.

Here is some code that works:

  <dtml-call "REQUEST.set('CurrentDate', ZopeTime().Date())">
  <dtml-call "REQUEST.set('mystring', 'date: ' + CurrentDate)">
  <dtml-var mystring>

Again, you've never set CurrentDate correctly. View the source of the page
that comes back and you will see the problem.

Hope this helps.
