In your previous message you said:

<snip>
Simple test methods in folder C

   <dtml-var standard_html_header>
   <dtml-let sss="scripts.cleanfilename('able baker charlie  ')">
   <dtml-var sss>
   </dtml-let>
   <dtml-var standard_html_footer>

work fine and do not throw the attribute error.
</snip>

Now you are saying that the static string does cause the error?


To remove the acquisition issue:  if you can get the cleanfilename routine 
to just return the input parameter (as a test, don't do anything else in 
cleanfilename) without error, then that means that you have a coding error 
somewhere within cleanfilename.
