I was looking for a way to change the color of an image using a slider. I decided to tweak some Javascript code so that it alters the opacity of a different colored image layered on top of the original one as the slider is adjusted. Additionally, I incorporated a dimming feature that utilizes opacity and a black overlay to dim the image.

Everything runs smoothly in Chrome and Firefox, but I can't seem to get it working in Internet Explorer. As a newcomer to Javascript, I'm struggling to pinpoint the issue. Any assistance would be greatly appreciated!

HTML

<div class="blackBoxDimmer" id="dimmer"></div>
<div id="slidecontainer">
    <input type="range" min="0" max=".99" step=".01" value=".5" class="slider" id="myRange">
