Each month a program adds a large amount of fresh data relating to the
previous month onto a spreadsheet called "data" which is hiden. On another
"Summary" sheet the fresh months data needs to be added and summariesd.

At the moment, each month I have to go to the Summary sheet, in order to add
another months data I first cut the summary from the end of the last column
and move it one column to the right. Then highlight the last months figures
and drag over to the now empty column (previously the Sumarised column)
which drags across the formulas to populate this months figures.

Then I have to go into the final summary colmn (which I have just cut and
pasted one column to the right) and adjust the formulas which now stop one
column short.

How is the best way to achieve the above, I tried creating a macro, but I
had a number of issues, mainly with trying to sellect the last column and
then last but 2 column.

I did wonder if I could hide say 24 columns (after draging the formulas
across them all first) then have the Summary, so each month I would have to
unhide one column.. but I would like to automate it and do not know where to
start. Any help most gratefully accepted.
