I am making a google apps script in which you give an image link and the desired width and height, takes the center color of the division, and puts it as the background color of the corresponding cell. I believe everything should be fine, but my color data is apparently not reaching my main function.

I’m progressively working through learning enough of HTML and javascript to apply to a google sheets package I’m developing for personal use. I developed a script from assistance on a previous post I made but am having some issues.
