I'm glad to help, although I feel compelled to let you know that it's not actually valid code to have a block level element (the <div>) inside an inline element (the <a>).
A better approach would be to separate the "welcome to Tralee" text from the background image. Then put the background image on the container itself (container_12). Then under the menu have the H1, and you could then move the actual H1 text off screen and replace it with the title image.
That way, you've got a more reliable setup that the validators will like too.
