Como inserir shortcode em um plugin

Amigos…
Sou leigo em php e gostaria da ajuda de vocês numa tarefa.
Tenho um plugin que lista os anivesariantes do mês e estou fazendo umas modificações nele. Uma das modificações que fiz foi inserir um shortcode [niver] para que eu possa exibir a lista em qualquer parte do post. Meu tema tem um arquivo só para armazenar shortcodes e lá eu inseri a seguinte linha:

add_shortcode('niver', 'nbday_month');

* nbday_month é o nome da função no plugin que gera a lista de aniversariantes do mês.

E deu certo (em partes)…

Quando coloco a tag [niver] ele retorna a lista de aniversariantes do mês gerada pelo plugin, porém não importa onde eu insira a tag, ela sempre aparece na parte superior ao texto.

Alguém poderia me ajudar a consertar isso?

Grato!

Leonardo, passa o código do seu shortcode pra gente dar uma olhada?
Mas ó, por cima, eu diria que você está dando um echo no shortcode em vez de um return, e por isso que ele sobrepõe todo o conteúdo.

Oi Eduardo!
Cara o código do plugin onde coloquei o shortcode é esse:
<?php
/*
	Plugin Name: Birthday List
	Description: A plugin which stores birthdates and displays current birthdays and 	either upcoming birthdays a  week prior to the event or the current months birthdays on the sidebar or footer and birthdays for the month on the admin page.
	Version: 2.5
   Date: 06/07/2009

/*
  Much of this code I modified from the Our ToDo List plugin and updated and added code from my original
  Birthday List.  The date validation function came from Softpedia.  I had to change the function name to
  make it work, though

	Function Name: date_validate

	Author: Eric Sammons, Vansam Software, Inc. (www.vansam.com)
	Email: eric@vansam.com

	Date: 2001-09-01
	Version 1.0.0

	Purpose:
		Receives various date field formats, validates them, and then and
		converts them to MySQL standard date format

	Valid date fields:
		dd-mm-yyyy, mm/dd/yyyy, yyyy-mm-dd, yyyy/mm/dd

	Returns:
		if valid input, the date in MySQL standard format
		if invalid input, error message with "Error:" at the beginning of message

	Sample Use:
		$MySQLDate=date_validate($datefield);
		if (substr($MySQLDate, 0, 5)=="Error") {
			// Insert Error Code
		} else {
			// Insert Valid Date Code
		}
