copy data

[cg1980]

Hi
in the attached file, i want to copy paste 3 cells on a monthly frequency.

If you open the file, you can see the structure I mean:

Each beginining of month, I copy the 3 groups of cells on the first colum on the right

For instance, fisrt column are in s1, then at the beginning of the next month (column A are the dates), I copy S1 S2 S3 and past in T22-T23_T24
I continue in this way up to the end of the data set.
thanks if someone could help
