Creating Functional Form

Hello all, I am attempting to add a Year, Make and Model search for my site and would like to know how to go about creating it. Below is a sample of what I assume would be “var” function but I am very new to coding and do not know where to start. I need this site completed as soon as yesterday :wink:
All help and suggestions are appreciate.

cars[“Acura”] = new Array(“1.6 EL”,“1.7 EL”,“2.3 CL”,“2.5 TL”,“3.0 CL”,“3.2 TL”,“3.5 RL”,“CL”,“CSX”,“EL”,“ILX”,“Integra”,“Legend”,“MDX”,“NSX”,“NSX-T”,“RDX”,“RL”,“RSX”,“SLX”,“TL”,“TSX”,“Vigor”,“ZDX”);

Kind Regards,
Brittani
