How do I pass the parameter, which in my case is quite long and stashed neatly away in a PT macro?

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

TIA,
Tony

You might check out the basics about HTML forms first. The 'action' parameter is an URL and *not* some Python-like function call. You specify the destination URL inside the action attribute and pass the parameters as *hidden* form parameters to the URL - either using method GET or POST.

You'll find more on forms in any HTML tutorial. Start from here:
