Hi All,

I have a complex description for what you will all find very easy. Im sorry if I dont use the correct terminology.

I would like a macro that inserts a column before column A.

Then I would like to fill that column with numbers 1 to 576 leaving every second cell blank and starting at row 12.

Then I would like it to place the data that got moved left next to the corresponding number.

I need it to then do some formulas. I would like it to work out the difference between the highest and lowest number in each group of 24 in a particular column

Perhaps it is better that I do a before and after workbook for you to look at.

Hope to hear from you shortly.
