Default attributes create page

I figured it out, but still can’t get Custom Fields to work.

Here it is:

Title: <input name="reply_title" type="text" value="" /> <br />
	<span style="display:none">Character:<input type="text" name="reply_character" value="" /><br /></span>
	Reply:<br />
	<textarea name="reply_content" id="reply_content" class="theEditor" type="text" tabindex="1" rows="15" cols="90" /></textarea> <br />
	<input type="hidden" name="reply_author" value="<?php
	echo $reply_login; ?>" />
	Password: <input name="reply_password" type="password" /> <br />
	<input name="reply_parent" type="hidden" value="<?php the_ID(); ?>" /> <br />
	<input type="submit" value="Post it!"/>

And then the replyprocess.php

<?php
	include_once( 'wp-includes/class-IXR.php');

	$method_name = "wp.newPage";

	$rpc_url = "http://www.wheeloftimerp.net/xmlrpc.php";
	$blog_id    = 1;
	$username   = $_POST['reply_author'];
	$password   = $_POST['reply_password'];
	$publish    = true;    

 	$custom_fields = array(
 		"key"   => "Character",
 		"value" => $_POST['reply_character']
		);

	$post = array(
	     "title"         => $_POST['reply_title'],
	     "description"   => $_POST['reply_content'],
		 "wp_page_parent_id" =>  $_POST['reply_parent'],
		"custom_fields" => $custom_fields
	);

	$rpc = new IXR_Client( $rpc_url );
	$status = $rpc->query(
	     $method_name,
	     $blog_id,
	     $username,
	     $password,
	     $post,
	     $publish
	);

	if( !$status ) {
	     print "Error in RPC request\n";
	     print_r( $rpc );
	     exit;
	}

	print_r( $rpc->getResponse( ) );
	print "\n";

	?>
