wp_insert_post issue

I’ve got the following code in the ‘functions.php’ file of a wordpress theme

$ppost_data = build_post( $pID, $pcontent, $pname, $ptitle, $pstatus, $ptype, $pset_comment_status );

wp_insert_post($ppost_data);

and here’s the ‘build_post()’ function:

function build_post( $pID, $pcontent, $pname, $ptitle, $pstatus, $ptype, $pset_comment_status ) {
return array(
    'ID'=>$pID,
    'post_content'=>$pcontent,
    'post_name'=>$pname,
    'post_title'=>$ptitle,
    'post_status'=>$pstatus,
    'post_type'=>$ptype,
    'comment_status'=>$pset_comment_status,
    'post_author' => 1
);

The variables are all set, and all of the data is in the $ppost_data array correctly, but the page isn’t being added. No errors are being thrown. Any ideas?
