Okay, I've got this line:
       <div tal:define="iter python:modules['ZTUtils'].Iterator(range(1000)); x iter/next">
and then use this kind of line several times further down and within the div:
                <input type="hidden" tal:attributes="value bitem/quantity; name python:'quantity_' + `x`">
What this yields is lines like this:
                <input type="hidden" name="item_name_1" value="17x25">
but it never increments! And I have 3 items! How do I get it to increment?
TIA,
Tony

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.
