Como Chamar função de previsão de tempo por geolocalização

[Antônio Sérgio]

Pessoal, fico com vergonha, mas esta vida de aprendiz .. :)

consegue uma função para mostrar o tempo de acordo com a localização do 

usuario, mas a vergonha não estou conseguindo chamar ela, 

ela está rodando no site www.terrenaagro.com.br

ela esta anexa e  abaixo:
