HELP: Display data based on user input

Hi, I'm new to this, and I am trying to create a process whereby a user on my site will be able to select a list of company names from a drop down menu, hit enter, then be shown details for that specific company. At that point they would be able to change/edit those values and save the results. Can anyone help?

I've been able to load some test data, create a form that pulls in the company list, but that is where I am stuck.

Thanks in advance!
