I don't know whether this is the same problem I had recently or not. But, 
anyway, for the <select ... multiple> tag, you are almost surely better off 
if you specify the ":list" switch in the name. That is, change NAME="styles" 
to NAME="styles:list". This way, it won't freak out when a single item is 
selected. The reason is: when a single item is selected and you don't have 
the ":list" suffix, the form returns a string instead of a list of one 
single string. I have no clue whether this is problem of HTML/Python/Zope... 
(I asked the question but got no answer, sorry.)

  <SELECT NAME="styles:list" size="4" multiple>
  <OPTION VALUE="" SELECTED>&nbsp;
  <dtml-in styles_list>
  <OPTION VALUE="<dtml-var sequence-item html_quote>"><dtml-var
sequence-item>
  </dtml-in styles_list>
  </SELECT>

hope this works,
