There is an important distinguishing characteristic between the 
type 'records' and 'record'.  'records' makes a list of record 
objects, 'record' makes a single one.

Change your python script to do:

for item in items:
	context.edit(amount=item.amount)

or change the HTML form to have:
name='item.amount:record' value='value typed'

If your form only has one 'item', you can just use the singular 
version.  If your form has multiple ones, use the plural, and then 
use the 'for...' loop in your python script.

Note that even if you only have one record when using the 'records' 
type, it still gets turned into a sequence.
