[Zope] External Method & LocalFS

[Belen.Ares-Paredes@symbian.com]

Hello there,

I have an External Method which takes as a parameter the basepath of an
LocalFS Object:

<dtml-let imagen=3D"Imagenes['logo.gif'].basepath"  >
<dtml-call "minipil(imagen)">
</dtml-let>

The external Method is a s follows:

#minipil.py
import Image

def conversion(a):

     im =3D Image.open(a)
     return im.format

Everything is very simple but I get the following error:
                                                                           =
