Hi Evan, Problem solved! I suddenly realised that the problem may have been the means by which I was trying to debug - I was using tal:content to view the variable and in doing so was causing it to be rendered, whereas just using a tal:define does exactly what you suggested and works properly! Many thanks for your help, Dominic --On 29 June 2003 15:31 +0100 Dominic Hiles <Dominic.Hiles@bristol.ac.uk> wrote:

Are you *positive* that it's getting passed to the template unrendered in the first place? Yep, absolutely - it shows up unrendered in the args list, it's just when I try to access it as a specific item from that list (via a python expression) that it's rendered.

Cheers,

Dominic
