Issue I'm having is I have a subroutine that scans any input data from A1 on. It scans for part of the equations by row and another part by columns. I was hoping to pop in some headers and sample numbers to make it more user friendly for the people to enter their data. Only issue with this is if I have headers and row numbers it calculates my data wrong. It counts the empty row because of that sample number and counts extra columns due to the headers. I wish I could tell it to only scan for the range excluding column A and Row 1.
