Ah, size is a _variable_, not a function/script/whatever ! 
Why don't You tell ;-)
In the original DTML version this read:

 <dtml-var "sizeCalc(204,size(_.None,_))">

this looks like "size" is a function ...

Maybe Your problem is that You do not have a merged undernamespace in
ZPT as in DTML, but have to be explicit where your thingies live. 
If its a variable defined with tal:define, sometimes a "global" helps.
Well, this time You did not mail an error message, thus its impossible
to guess whats the problem.

Could You please tell what Your "size" is, and where it is defined
normally?
