Hi Shawn - we would be happy to assist but I would recommend taking a look at this free app to achieve what you want to do; it works very well:
https://apps.shopify.com/quick-announcement-bar-always-keep-your-customers-informed
We have used this on a variety of sites (example: https://www.bbqing.com) and it does the trick.
Hit us up via email at projects[@]whitewatersolutions.com if you need a hand.
Cheers!
