Hi

I'm getting the following issue when the add to cart button is clicked.

Parameter Missing or Invalid: Required parameter missing or invalid: items
Password:paulkaz
I recently installed the Order Printer Pro: Invoice App, but uninstalling it doesn't help.
Any help would be appreciated.
Thanks

The issue is with this script:

<script type="text/javascript" src="{{ 'js-image-zoom.js' | asset_url }}" </script>

The code is below, there must be a conflict here that I'm yet to figure out.

 

(function (root, factory) {
if (typeof module !== 'undefined' && module.exports) {
module.exports = factory();
} else {
root.ImageZoom = factory();
}
}(this, function () {
/**
* @param {Object} container DOM element, which contains an image to be zoomed (required)
* @param {Object} options js-image-zoom options (required)
* **width** (number) - width of the source image (optional)
* **height** (number) - height of the source image (optional).
* **zoomWidth** (number) - width of the zoomed image. Zoomed image height equals source image height (optional)
* **img** (string) - url of the source image. Provided if container does not contain img element as a tag (optional)
* **scale** (number) - zoom scale. if not provided, scale is calculated as natural image size / image size, provided in params (optional if zoomWidth param is provided)
* **offset** (object) - {vertical: number, horizontal: number}. Zoomed image offset (optional)
* **zoomContainer** (node) - DOM node reference where zoomedImage will be appended to (default to the container element of image)
* **zoomStyle** (string) - custom style applied to the zoomed image (i.e. 'opacity: 0.1;background-color: white;')
* **zoomPosition** (string) - position of zoomed image. It can be: `top`, `left`, `bottom`, `original` or the default `right`.
* **zoomLensStyle** (string) custom style applied to to zoom lents (i.e. 'opacity: 0.1;background-color: white;')
