[Zope] filename property of variable

OK tried the REQUEST.form only etc. It still doesn't differentiate between a
file box filled in and one not filled in.
Also in answer to your question - there are Specimen objects with these
names and they are in the same folder as the method is executing in.
OK so here is my take on what is happening - the method is running and when
the _[_['sequence-item']] runs it looks up in the current context (REQUEST
is always last in the aquisition path) and finds the specimen objects and
returns them rather than the file object I want to upload - I guess that I
can put an extra piece of information in the name of the file box on the
form and then strip it out when I want to add the image to the specimen. If
I use the only syntax, I then will not have access to the Specimen that I
wish to add the image to.
Is this going to be the easiest way of achieving my goal???
Laurie
PS Thanks for all your help!

OK, I think we're making progress. Will you post the html form AS RECEIVED
BY THE USER'S BROWSER? You have already posted the dtml for the form, now
let's see the rendered form.
Also, the "html source" that you show below - is it what you see on the
screen when the form handler runs? Because if looks like the page is
finding Speciman objects of the same name as the form variables - maybe from
earlier runs? Maybe that could be stopped by using ONLY (I forget if it's
upper or lower case):
<dtml-with "REQUEST.form" ONLY>
<dtml-in keys()>
<!-- and so on -->
</dtml-in>
</dtml-with>
