Correct syntax for multiple product ID's for Google Ads in GTM

Question

I'm using Google Tag Manager to pull in some data for my Google Ads. When I goto a product page, I've just hard coded some product ID's as an example, but I get the following error:

This is how I've defined the product ID's, it's saying multiple ID's need to be in an array, to my understanding they are.

Where am I going wrong?

Try to use your GTM variables {{order-items}} (that contains in your case 193, 194, 195) in a Custom Javascript Variable to generate an array from your comma-separated string, like this:

function() {
  var products = {{order-items}};
  return products.split(",");
}
