Auto populate item description and price from drop down menu

Hi @cynthiac80143548,

Hope you are doing well. Thank you for writing in!

You might want to try the below script once: 

function autoPopulateItemDescriptionAndPrice(dropDownField, descriptionField, priceField) {
  // Get the value of the drop down field
  var selectedValue = dropDownField.value;

  // Get the description and price for the selected value
  var description = "No description";
  var price = 0;

  switch (selectedValue) {
    case "Item 1":
      description = "This is item 1";
      price = 100;
      break;
    case "Item 2":
      description = "This is item 2";
      price = 200;
      break;
    case "Item 3":
      description = "This is item 3";
      price = 300;
      break;
    default:
      break;
  }

  // Set the description and price fields
  descriptionField.value = description;
  priceField.value = price;
}

// Get the drop down field, description field, and price field
var dropDownField = this.getField("DropdownField");
var descriptionField = this.getField("DescriptionField");
var priceField = this.getField("PriceField");

// Auto populate the description and price fields
autoPopulateItemDescriptionAndPrice(dropDownField, descriptionField, priceField);

Note: I am not an expert in scripting, which may or may not work.
