Now let's add some context to your 'simple_page' template, in the
form of a list of the objects that are in the same Folder as the
template. You will make a table that has a numbered row for each
object, and columns for the id, meta-type, and title. Add these
lines to the bottom of your example template::
<table border="1" width="100%">
<tr tal:repeat="item container/objectValues">

ERROR! should read "td tal:content="item/number">#</td>

No, actually it should read exactly what it says there.
The explanation for why it should have the "repeat/" before it is quite bad, though.

Nevermind, it makes sense now:
'repeat' is a variable.
no object in the 'item' array has a 'number' attribute
so to number everything, you need to write 'repeat/number' to get the 'repeat' variable's 'number attribute'
since the tal:repeat may be nested, 'repeat/number' is ambigious in this context, so:
makes sense now :)

Yes, it does make sense if you pay attention and read below. I think that the explanation is quite
reasonable, but the distinction between "repeat/item/number" being a reference to the repetition number, and
the "item/getId" being a reference to an attribute of the item in question is not immediately clear. If you
think about it, it is, but a clear statement of the distinction would be useful.
Incidentally, an example of a nested loop may have cleared this up a little by encouraging a little bit of

horrible syntax :-\

What do you do if you have an SQL join and want to display both to the screen
Two Tables - one called users one called items
a query that matches the id of someone who made an item vs the id and username in the user table. I cant do
<div tal:repeat="items user here/blah/method_thing"></div>
