cannot export the framemaker graphic element

Hi you,

I need some help for exporting graphics on translation to XML. In general FM exports a changed graphic into a new *.cgm file. This works. Now I'd like to change the format to eps and wrote the read/write rules:

     element "Grafik" { is fm graphic element;
                               writer anchored frame export to file "$(entity).eps" as "EPSI";}

When I save the FM document to XML, the message occurs: cannot export the FrameMaker graphic element () into the specified graphic format.

The XML will be created an also the entity for the graphic, but not the needed graphic file. What is wrong?

Thanks,
