Thanks very much for taking another look at my problem.

Here's the best my brain could come up with
<%# = button_to_function("ShowList",
%<page["vendor_droplist"].toggle> ) %>
<%= button_to_function("ShowList")
{ page["vendor_droplist"].toggle } %>
but compilation of new.html.erb with that change gives me:

===
undefined local variable or method `page' for #<ActionView::Base:
0x467eaf4>

Extracted source (around line #17):

14: <%= f.label :vendor %><br />
15: <%= f.text_field :vendor %>
16: <%# = button_to_function("ShowList",
%<page["vendor_droplist"].toggle> ) %>
17: <%= button_to_function("ShowList")
{ page["vendor_droplist"].toggle } %>
18: <br />
19: <div id="vendor_droplist" style="display:none">
20: <%= select_tag "list",
===

If it's not too much trouble, can you point me to website that
provides detail on the alternative forms, or even better, show me a
correct form of #17 above. Sorry for being so obtuse ... I'm a Rails
nubie, but aspiring higher :-)
