I have a very basic SUM formual in my smartsheet. The resulting number is 2 more than it should be. I've cleared the forumla and built it from scratch, and double checked the data in the column. If I handcount, I get the right answer, but the SUM consistently is 2 over. Simiarly, in the next column, I have a COUNTIF formula ... again, 2 over. What am I doing wrong?
