For years I have used this statement to include simple

For years I have used this statement to include simple content in a file:

<?php include(TEMPLATEPATH.”/includes/filename.php”:wink:;?>

This way the client can add simple content to areas like footers by using a basic HTML editor. I tried using this statement in the SimpleMarket theme with no luck. I am using WordPress 4.2.2. There are no errors, it just does not load. The file has html and no scripting.

Perhaps a better question is: how to I add an INCLUDE or REQUIRE statement to SimpleMarket?
