I am trying to fix my php text widget code; it should display a scrolling box with contents from a URL on my site (http://worldesquire.com). It is on homepage and shows :404 error page not found.
Existing code: <div><iframe src="<:?php echo home_url ( ): ?>/wp-content/themes/lawfirm/content.html" width= "100%" height="400"></iframe><div>
URL I want to display: http://worldesquire.com/?page_id=302
I need help doing it. I can't write code. I don't want to mess it up any more than i already have. Thanks.
