I have a master sheet and another sheet called January. I have set them up to where data that I input in the master goes to the appropriate place on the January sheet. Now I am done with January. I need to lock it somehow so that the new information I put in the master will go to another sheet called February. In other words, each month, I will have new #'s to go on the master sheet, which then needs to go to the new month sheet. Is this possible? Thanks!
