So you have a form with different element names each time?
You access REQUEST via context.REQUEST
if you dont know if REQUEST or its sub element form
has a given key, you can use the standard python
mapping interface (see documentation for dictionary)

This for example has:
context.REQUEST.form.has_key("nameofyourvar")

which returns True if this variable has been sent

context.REQUEST.form.get("nameofyourvar",defaultvalue)

which would return the value of the form element
if sent or the defaultvalue otherwise.
