This should be simple but for some reason it is not. I am using Executable PHP widget to place some coding within a right inner sidebar. I created a custom field named "callout_text" that is used to display a sentence or two as a callout of the current post. Within the widget, the code I am placing is:

<?php callout_text(); ?>

However, when displaying the page, I get the following error message:

Fatal error: Call to undefined function callout_text() in /home/content/r/p/n/rpnimchuk/html/wp/wp-content/plugins/php-code-widget/execphp.php(37) : eval()'d code on line 1

What the heck am I doing wrong? BTW I am using Custom Post Limits to limit the home page to a single post. I am also using WP 2.8.5 and the latest version of Atahualpa.

Thanks!

when you use the syntax 'xxx()' php believes that you are calling the function 'xxx' so somewhere in the code there hast be
HTML Code:
function xxx(parms) {
   some
   code
   goes
   here
   }
the error is saying that php can't find the callout_text function

Thanks Juggledad. Found the error of my ways. I needed to place the following code in the widget:

<?php
global $post;
echo get_post_meta($post->ID, "callout_text", true);
?>


Because this is contained within a widget you also need to declare the scope (global $post) to return the information. This works great for how I want to display part of blog's content as call out text.
