Querying a complex website

[schweet1]

Greetings,

I am attempting to use python to submit a query to the following URL:

https://ramps.uspto.gov/eram/patentMaintFees.do

The page looks simple enough - it requires submitting a number into 2
form boxes and then selecting from the pull down.

However, my test scripts have been hung up, apparently due to the
several buttons on the page having the same name.  Ideally, I would
have the script use the "Get Bibligraphic Data" link.

Any assistance would be appreciated.
