If the widget code does not work, you will need to add a new script after the script is taken from Instant Inventory.

Example of the original Jewelry Widget Script

2. Add this new script after the Widget Script

<script>
var func = function() {
var d = document.getElementById('jewelryinstantinventory');
var i = document.createElement('iframe');
var apiKey = d.getAttribute('data-apikey'); i.id = 'jewelryRapnetIframe';
i.name = 'jewelryRapnetIframe';
i.width = '100%';
i.height = '100%';
i.style = 'border:none;';
i.setAttribute('data-apikey', apiKey);
i.src = 'https://ii.api.prod.rapnet.com/api/Feeds/%APPKEY%/Widget#/'.replace('%APPKEY%', apiKey);
d.appendChild(i); i.onload = function() {
i.contentWindow.postMessage({ apiKey: apiKey }, '*');
};
};
func();
</script> (edited)
