If author doesn’t equal admin echo [code]

Hiya, I am trying to only show the following code when the author isn’t admin. I have spent ages trying to mess around with conditions trying to exclude the author so I am obviously doing something wrong.

Any help would be most appreciated.

Many thanks
Alex
