copy and paste macro
 

I need help creating a macro to copy cells C3:C22 and then PasteSpecial,
ValuesOnly to cells O12:O32. Then the next time I run the macro, I need it
to paste the C3:C22 values into the next available blank column, P12:P32. It
has to be able to do that for a total of 12 times, each time using the naxt
available blank column. It then has to automatically erase it all, O12:Z32.
Then it would start over with the O column again.

I would appreciate it if somebody could show me the complete macro to
accomplish these steps. Thank you.
