I'm using an Excel DDE to connect to Interactive Brokers TWS via their API 9.72 sample, excel 2013. When I tried to create a combo order, the rum error code 424 said "object required". It seems that something is wrong with the "ComboLegForm" Userform. The code is too long to paste here, and I don't find anywhere I can attach the file. The xls file is located in TWSAPI/samples/Excel/TwsDde.xls

Thank you for helping.
