Necesito Ayuda

[Pelgriego]

Hola, tengo un inconveniente que no puedo solucionar, he colocado un Foro en mi sitio y no puedo borrar los mensajes .
Mi conocimiento de javascript es muy elemental.Aclaro que "citar" y "modificar mensaje" funcionan correctamente.
Si alguien puede ayudarme aqui coloco el archivo que supongo tiene el error. Gracias
