filter van os commerce

hoi ik ben bezig om een webwinkel van os commerce op te zetten.
wanneer je daar een categorie aanklickt krijg je een opsomming van alle producten ( van de categorie) en hier kun je dan ook op manufacturer filteren doormiddels van een dropdown-menu.Er vallen dan alle producten weg die niet erbij horen.Dit bevallt me heel goed en daarom will ik hier meer filters hebben , bijvoorbeeld ook op kleur filteren.
Nu ben ik zo ver gekomen, dat ik dezelfde soort filter ernaast heb waar je op kleur kunt filteren en deze doet het ook. MAAR samen doen ze het niet.Je kunt de manufacturer-filter zien en ook kiezen ,maar er gebeurd gewoon niets.Ik moet in de php-code de regels die voor de "kleur-filter"veraantwordelijk zijn dorr /* */ op non actief zetten om weer de "manufacturer-filter" te laten werken.
En nu ben ik ook aan het eind van mijn php-kunnen gekomen en heb wat hulp nodig om ze samen te laten werken.Bedankt voor de moeite alvast.

Nu komt de code die voor de filters zorgt:
