I have tried to put a Facebook like button on my website but can't get it working properly. The number of likes only shows as one and if I click it again goes to zero. Surely it should show the total amount of likes on my Facebook page.

This is how I have done it.
https://developers.facebook.com/docs...ns/like-button
Filled in the URL, width, layout and action type
Clicked Get Code
Clicked on iframe
Copied and pasted code onto my footer on my webpage.

But this does not work, any advice on where I am going wrong please.
