[Zope] CMFReportTool error Message

[Peter Millar]

Are there any CMFReportTool experts out in the plone/zope world??

I think I have set up everything properly . when I call 

http://localhost:5555/devel/index_html/asPDF/pdftemplate_default/documen
t_pdf

This error appears .

Error Type 
AttributeError
Error Value 
'NoneType' object has no attribute 'lower'

Traceback (innermost last):
  Module ZPublisher.Publish, line 100, in publish
  Module ZPublisher.mapply, line 88, in mapply

  Module reportlab.lib.fonts, line 104, in ps2tt
  Module string, line 55, in lower
AttributeError: 'NoneType' object has no attribute 'lower'

The offending line in function ps2tt I think is 

def ps2tt(psfn):
    'ps fontname to family name, bold, italic'
**    psfn = string.lower(psfn) 			UGLY LINE
causing problems **
    if _ps2tt_map.has_key(psfn):
        return _ps2tt_map[psfn]
    raise ValueError, "Can't map PS font %s" % psfn

Any ideas anyone . have I missed something somewhere??
