[SOLVED] Comments error on single page

When I go to view a single page, this error comes up:

Fatal error: Call to undefined function boposts_show() in .../wp-content/themes/atahualpa/functions/bfa_postinfo.php(594) : eval()'d code on line 5

in bfa_postinfo.php, starting on like 589, is this code:

/* PHP code in Post Info Items.
But not for WPMU */
/*removed in 3.4.3. - PHP code works in WPMU too */
if ( strpos($postinfo_string,'<?php ') !== FALSE ) {
ob_start();
eval('?>'.$postinfo);
$postinfo = ob_get_contents();
ob_end_clean();
}

making like 594 - eval('?>'.$postinfo);

when i remove this code, the page works. Anyone have any ideas why this might cause an error on a single page?
