Maybe you'd like to explain what a wing Mathcad sheet should be, where you have it from, what you mean with cfdrootsection and cfdtipsection and what you are trying to do at all.
If your question does not belong to one of the sections I had pointed you to, I guess you are better off in posing that question in the Creo secton of this forum. But I still think that you want to post in the RWDC section, the first link I supplied.
