Joomla Component Tweaking

URL to the working component is: [login to view URL];Itemid=119 I need to edit how the component works. At the moment I have three db tables. 1. Events: 2. Locations 3. Questions HOW COMPONENT CURRENTLY WORKS ========================================= 1. Create a location which shows up in frontend location drop down list. ([login to view URL], enter name and save) 2. Create an event, The compass challenge for example. ([login to view URL], enter details and save) 3. Create a question, Orienteering for example and assign the relevent events to it. These are the frontend checkboxes. On form submission it shows the details of relevent events. ([login to view URL], enter details, assign event and save) ========================================= WHAT IS NEEDED ([login to view URL]) ========================================= I want to create an event and assign questions and locations to it (see [login to view URL]). So when a user fills out the form, eg Location Dublin, and checks the Orienteering box. It will pull back all events that include orienteering in Dublin. There is no currently no link between events and locations. I need this project done asap.
