Ola Pessoal, Tenho uma pagina que está rodando o google maps na v3

Acontece que eu uso 2 repeaters dentro do javascript que recebem dados de uma procedure em SQL que é feita em vb.net

Até ai ele esta recebendo estes dados normalmente, só que o mapa não carrega de forma nenhuma

Será que alguém poderia me ajudar???
