Здравствуйте, подскажите пожалуйста, прописываю вот такой код:
firmid = «XXXXXXXXX»;
client_code = XXXX;
limit_kind = 2;
cena = getPortfolioInfoEx (firmid,client_code,limit_kind, portfolio_value)
message (""..cena)
Но выдает ошибку:
attempt to concatenate a nil value (global 'cena')
Подскажите в чем проблема
