Assistance to get the right filters in listings and selects

I have a problem with filtering and showing the correct listings of pitches (advertising's). Code is done so far. Only need assistance to get the right filters active so listings are correct shown. Info: When opening the pitches page you will get the latest 5 ads without a filter active. If you want to show a specific listing the you have to select Select Group + Select Country else you only get the latest 5. There is no select box active despite first file Select Group. You can filter on 4 target groups: Retailers – Agents – Wholesalers – Companions. If selected for example Retailers the second select box is now active too: But selected is not shown in listing. When you start filtering select box Select Country is now also active. If you select a country like France you will get a new listing showing the filtered data. Now you can filter also on Select Date or Company Types . When using these filters the listing should be updated. Stream: Show 5 latest pitches ▼ Select Group (no action in listing) ▼ Select Country (listing is now changed) ▼ Show filtered pitches ▼ If select Date or Company Type ▼ Show filtered pitches selected on Group + Country + Date and / or Company Type This tiny project is the start for a lot more work in same project.
