Design a webpage for a mobile phone that allows a display information after selecting from a dropdown list

Build a single webpage with two dropdown lists and a button to first filter then display information in a couple of labels. 1. User first picks from one dropdown list which filters the next dropdown. 2. User presses the button to see details of the selected dropdown list displayed in some labels. Data within the dropdown list will be coming from a SQL server database which are already set up along with stored procedures. Dropdown list just needs to be passed. All bids considered Ask any questions and I'll clarify.
