It looks to me like the part here that you don't understand is how to
interpolate your form data into the string for the database query.

You should study up on the % string formatting operator in the Python
docs.

I'll throw you a bone here;

"""
%s %s %s
""" % (form[key1].value, form[key2].value, form[keyN].value)

Each of those %s tokens is going to be replaced with one of the values
in the tuple right of the % operator.

If you want to pile the form values into a dict and then use symbolic
names in the string...

dict = {}
for key in form:
	dict[key] = form[key].value

"""
%(key1)s %(key2)s...
""" % dict

Maybe there is a function in the cgi module that will make the dict
for you?  I am not sure.

Have fun!
