Same problem as before but I got cut off...
I'm trying to create a list of the running total of the number of unique values in column G. So the list should look something like 1,1,1,1,2,2,2,2,2,3,3,3,3....,74,74,74 etc. The attached file is just a sample, the full data set of 80,000 was too large to upload.
