Hello ,
Down here we have my code and the error in the compilation, and i dont know how to resolve this can anyone help me.
Just a introduction:
This python script is used to save datas from a form in sql_data base.


# Available parameters:
# fields = HTTP request form fields as key value pairs
# request = The current HTTP request.
# Access fields by request.form["myfieldname"]
# ploneformgen = PloneFormGen object
#
# Return value is not processed
# Pega as variáveis do Ambiente

################################################
request = container.REQUEST
RESPONSE = request.RESPONSE

################################################
# Recebe os valores da Pagina
################################################
cliente = request.get('Cliente')
equipamento = request.get('Equipamento')
local = request.get('Local')
numero_da_proposta = request.get('Numero_da_proposta')
valor_da_proposta = request.get('Valor_da_proposta')
documentos_de_referencia = request.get('Documentos_de_referencia')
nome_do_autor = request.get('Nome_do_autor')
nome_do_checador = request.get('Nome_do_checador')
data_de_inclusao = request.get('Data_de_inclusao')
arquivo_pt = request.get('Arquivo_pt')

################################################
# Insere as informações no banco
################################################
context.adicionarAoBanco(Cliente=cliente,Equipamento=equipamento,Local=local,
Numero_da_proposta=numero_da_proposta,Valor_da_proposta=valor_da_proposta,
Documentos_de_referencia=documentos_de_referencia,Nome_do_autor=nome_do_autor,
Nome_do_checador=nome_do_checador,Data_de_inclusao=data_de_inclusao
,Arquivo_pt=arquivo_pt)

return "Ok"

Now here we have the error:
