[F8] Pulling Custom Image From 2 ComboBox Option Lists

I'm working on a project where a client has customization options for their product. The two options are the Cabinet Woodgrain, and the Backlighting Color. All-in-all, there are 40 different options that are possible. We are developing an ad that shows off a few of these, but I would love it if viewers could "customize" their product right within the banner ad.

Obviously, these need to be loaded seperately, or the loading would take too long for a banner ad. I have created two comboBox components with the options filled in already, a component button, and a Loader component. I want someone to be able to choose their two options, click customize, and have the correct photo load.

My code isn't working below, but I'm more of a designer than coder. Would anyone have a better suggestion on how to accomplish this? Much thanks!

Code:

---

on (click) {
        var cabinet = cabinetbox.selectedItem;
        var backlight = backlightbox.selectedItem;
        var jpglocation = (cabinet+backlight+".png");
        VoyagerLoader.contentPath = jpglocation;
}
