dropdown date

Hey,

i´m new in screen scraping. i like to know how you scrape a dropdown date form.
for example:
i have a dowpdown day - month - year form
i like to scrape the day´s and then a name and price on that specific day - month - year.
i know how to scrape one day but not the whole month or year for a specific detail.
can somebody help me?

best regards

Oliver
