Follow below steps.

step 1 – Pass context from Form to Web Resource using Form on load

on Form on load call the below method. make sure to use correct web resource name.

// This should be in a script loaded on the form. 
// form_onload is a handler for the form onload event.
function form_onload(executionContext) {
    var formContext = executionContext.getFormContext();
    var wrControl = formContext.getControl("WebResource_new_1");
    if (wrControl) {
        wrControl.getContentWindow().then(
            function (contentWindow) {
                contentWindow.setClientApiContext(Xrm, formContext);
            }
        )
    }
}

Step 2 – Edit HTML Web resource to read the form context

you can now use script to read context and declare global variables to use.

use below code in HTML web resource.

<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<style>
* {box-sizing: border-box}

img {vertical-align: middle;}

  margin: auto;
}

/* Next & previous buttons */
.prev, .next {
  cursor: pointer;
  position: absolute;
  top: 50%;
  width: auto;
  padding: 16px;

  font-weight: bold;
  font-size: 18px;
  transition: 0.6s ease;
  border-radius: 0 3px 3px 0;
  user-select: none;
}

/* Position the "next button" to the right */
.next {
  right: 0;
  border-radius: 3px 0 0 3px;
}

/* On hover, add a black background color with a little bit see-through */
.prev:hover, .next:hover {
  background-color: rgba(0,0,0,0.8);

.text {
  color: #f2f2f2;
  font-size: 15px;

/* The dots/bullets/indicators */
.dot {
  cursor: pointer;
  height: 15px;
  width: 15px;
  margin: 0 2px;
  background-color: #bbb;
  border-radius: 50%;
  display: inline-block;
  transition: background-color 0.6s ease;
}

.active, .dot:hover {
  background-color: #717171;

.fade {

@keyframes fade {

/* On smaller screens, decrease text size */
@media only screen and (max-width: 300px) {
  .prev, .next,.text {font-size: 11px}
}

input[type=text], select {

  padding: 14px 20px;
  margin: 8px 0;
  border: none;
  border-radius: 4px;
