[Zope] Displaying the text from a text area

[Robert Leftwich]

Problem 1 occurs because you are using the same name on form 2 for the
notes field and this field already exists in the REQUEST from the
previous form, which causes Zope to concatenate them into a list.
A simple fix is to use different names on each form.

Problem 2 can be rectified by using the newline_to_br format on your var
i.e.

<!--#var "notes" newline_to_br -->

which as you can guess converts cr/lf's to <br>'s
