This action is rubbish. I have no idea what you're trying to do.

What's this macro got in it?

Exactly, you've made up your own syntax there, so no wonder it doesn't 
work ;-)

Changed what to what?

I think you quoted the code for this earlier in the thread, it was 
attempting to use a query string parameter as part of a form action.
That *does not work*, nothing to do with Zope, that's just html.
You need to put doc as a variable in the form:

<td tal:define="docs here/CheckOutAfterEditStuff">
  <form action=http://example.com/s/renumberTheCart" method="post">
  <input type="whatever" name="doc" value="whatever"/>
  <p metal:use-macro="here/CheckOutAfterEditStuff/macros/main" />

I have no idea what the tal:define is supposed to do there...

Learn to crawl before you attempt walking, let alone running...
