Ok, I have changed my form element to what you suggested. These are the
results I am getting with various <dtml-call> tags in the VProduct_add
method (called after filling in VProduct_addForm):

* <dtml-call "REQUEST['file'].read ()">

Error Type: TypeError
Error Value: argument file was ommitted

I guess this is because no field in the form is named 'file'. So I try:

* <dtml-call "REQUEST['file_name'].read ()">

..and I get the same error. I even tried to name="file:file" in the form
element, and using REQUEST['file'].read () in the call, but then I get:

Error Type: AttributeError
Error Value: 'string' object has no attribute 'read'

which I guess means that it now has the 'file' variable, but it is still
a string.

Any other pointers, or references to where I can read more about the
file stuff?

Thanks in advance,
