Why aren't the next and previous product image arrows loading in my Buy Button?

[ABCS]

Hi

Just in the process of creating a buy button - everything works smoothly except the arrows for the next and previous product image arent loading.

The console tab of chrome dev tools is throwing a "Failed to load resources" error.  The culprit is with the source for the arrow: src="//sdks.shopifycdn.com/buy-button/latest/arrow.svg"

If I replace the src with "https://sdks.shopify "..... etc   the image loads fine.  As the source is loaded in the javascript of the buy button I cant figure out a way to manually correct this.  Anyone have any advice?

Thanks

For anyone interested - I figured it out.   Technically there was nothing wrong but I will elaborate.

Basically the supplied src was beginning with "//" which is essentially shorthand for whatever protocol is currently being used.   It didn't occur to me at the time that because I was viewing the site locally (but fetching the javascript from the internet) that the script would default to a local source for the images.  

When I eventually tested on a live server, the current protocol was then web and it sourced the images correctly.

Ultimately nothing to fix - and a simple oversight on my part.
