Good day, I want to source of an image based on the selection of a form. I made a bunch of assets for all the possible different selections, as seen on the attached image. When a change is made to the right a change must be made to the left image. This leads me to the following questions: How do I access the URL of all the images? How do I now which radio button/text box is active? How do I access the onclick or onmouseup etc events of the buttons within the form. I have experience in JS, HTML and CSS I just do not understand fully how I can add custom code to squarespace?
