I'm trying to use JS to dynamically replace an image on a page based upon the value of the selected option of a select dropdown. Everything in the code I've included below works perfectly. My selected_text variable is properly pulling the value of the selected option in my select dropdown, but I need to somehow write that value to the replacement img src path.

IE: If someone selects Audi from my select dropdown, I want to write Audi where I have [selected_text] in my replacement img src path.

Any ideas?

<script type=text/javascript>

function popmake() {

    var w = document.vafForm.make.selectedIndex;

    var selected_text = document.vafForm.make.options[w].text;

    document.getElementById('make-image').src=/path/to/images/[selected_text].jpg;

}

</script>
