You should now have all the parts.
Instead of iterating over python:range(1000) do it on bitem_ids instead.
You don't have to use a <br /> tag. You can use
<input tal:attributes="value iter/number" />
if you want.
You increment it by calling tal:iter/next whichever way you do it.

I would think this should be pretty easy in the PT itself, given what
you've shared so far. But I'm still not quite there. Here's what I've got:
<span tal:repeat="bitem_id bitem_ids" tal:omit-tag="">
<div tal:define="iter
python:modules['ZTUtils'].Iterator(range(1000))">
<br tal:define="x iter/next" tal:replace="iter/number" />
Now, I don't really want that <br /> tag there, because it's printing a
number to screen that I don't want there. However, it only prints the
number "1" twice, once for each product, when it should print 1 then 2,
I would think. (I presume I should just take the tal:replace out and
leave the definition, but it's still not incrementing!) Later in the
script I have this:
<input type="hidden" tal:attributes="value item/name;
name python:'item_name_' + `x`">
<input type="hidden" tal:attributes="value item/id; name
python:'item_number_' + `x`">
and other similar lines. What I'm trying to effectuate is that the "x"
gets replaced with an incremented number. Can you help just a little more?
TIA,
Tony

You can use the ZTUtils Iterator()
<div tal:define="iter python:modules['ZTUtils'].Iterator(range(1000))">
<br tal:define="dummy iter/next" tal:replace="iter/number" />
<br tal:define="dummy iter/next" tal:replace="iter/number" />
<br tal:define="dummy iter/next" tal:replace="iter/number" />
</div>
Which might give you some freedom such as iter/Roman or iter/odd
The above is practically the same as:
<br tal:repeat="i python:range(3)" tal:replace="i" />
Generally, if you can, use a Python Script or something. The Iterator
is/was used in Plone templates to increment the tab index.
