Range Manipulation Question
Dear All
I have a worksheet with 3 columns (see below). I need to cycle through
the data and for each group of rows with the same value in column 1, I
perform a stepwise linear interpolation to determine the value in Col3
corresponding to a value of 30 in Col2. I have a function set up for
the interpolation, but I am stuck on the code for cycling through the
range? Any help would be much appreciated.
Thanks
Matt
