Linked In Custom Button Showing Up As Facebook Button

I have just add a custom Linked In share button on my home page, coded just like the other ones, but it is showing up on website as a FB icon (linking to Linked In). Is there something different from “linkedin-share” that I should be entering? Can anyone find my error below? Thanks!

• <a class=”LinkedIn-share”
