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.
