Also, I am sorry, but I seem to have gotten ahead of myself XLadept.

The aforementioned code works in the sense that it populates the correct values, in a given instance.

However, it does not recalculate when I change any cells. This is something that it has to be able to do; the gist is that my colleague will be able to create this "topline" prior to the start of a program and successfully update it until the program ends.

Thanks for further insight!
