Hi *, I have a folder which contains a bunch of ZPT's and images, some of which share the same unique ID as a ZPT which a ".jpg" extension. ie. 1000 1000.jpg 1001 1002 1003 1004.jpg 1004 I have an index_html object which will render any ZPT in this directory and the matching image, if available. If there is no matching image I want to display an "image unavailable", but can't get this to work. <span tal:define="image string:${here/id}.jpg"> <span tal:replace="image"></span> <span tal:condition="not:python:here.objectIds(image)"> There are currently no items available. </span> </span> Regards, Michael Fox ^-^ Analyst/Programmer <`-`> ___ Century Software ' `' '.
