Hi. My situation is this:

I have a Word document, where I write down some numbers. To get these numbers, I need to open an Excel sheet, and calculate them using some primary values and functions I already have, then copying them. What I'd like to do, is just writing down the primary values in the Word document and have automatically calculated the resulting numbers by word, without the copy-paste proccess that I always do.
I have read about linking sheets or macros, but I haven't got a clear idea of what to do.

Hope it is clear. Thanks in advance
