What do you want tasks 17 and 18 to do?

What do they do instead?

Without being able to see your file the comments are of limited use:

' Task 17: Copy data from column T of "Calculations2" and their corresponding cells in column V of "Calculations2"
    ' Only copy data if the corresponding cells in column V are not 0 or 0.00
Does "corresponding cells" mean "the same row"?

Where do you want to copy the data to?
