Run your if statement like this:
<?php if (WA_getCMSContent($database_localhost, $localhost,"in focus", "Main area") != "" ) {
echo WA_getCMSContent($database_localhost, $localhost,"in focus", "Main area");
}
?>
Make sure you use "!=" when testing for Not Equal To.
Also, don't use the word "blank"... just two back to back quotes with no string between like this "" will signify empty.
