HELP--update function not bringing all values over despite 100% certainty I am matching
Hi--I am very familiar with the UPDATE function and use is often. I am trying to bring over a column of data from a new set into my master set. Both datsets have the SAME subject IDs (and same amount, N=110 in both). When I update, it only brings over 52 of the values. The rest are missing and I am absolutely stumped because I know I used update correctly and matched correctly
