Thanks Lana for the assistance. In my shopify store, when I attempt to change the header to become my logo, the header doesn't change and it won't let me save (save button stays green). 

Hello Shopify,  I am here due to a problem I have been facing while editing my online store. I am new to Shopify so I am unfamiliar with certain controls so I am asking for a solution to fix the save button not working. Thank You,Marc Smith
