I have an composite array of data in my Worksheet. I am using a Vlookup function to process the array for various algorithms which require data from the array. The composite array is horizontally divided by three rows of irrelevant data ("IR Data") into two arrays (upper and lower) which requires that the Vlookup function be initialized differently in the upper and lower array; i.e., the starting row of the lower array (below the IR Data) changes with varying output that populates the array.
