Hi SAS communities,   I match merged 4 data sets into one. There should only be 1 observation per person, which includes the most recent visit. One data set had a Birth Date variable and another data set had a Visit Date variable. After merging all 4 I then had to create a new variable that shows what age the person was between Birth date and Visit Date. Below is my code and I think I did the code correctly, but in the log, it shows that 2 out of the 573 are missing data. I checked the data sets and they show both the Birth date and Visit date. It could possibly be the way I also made the 4 data sets, but want to know ifs a simple coding mistake. Below is my code and a screenshot of the partial log.       Let me know if you need more information Thank you. ... View more

Hello SAS Communities, I've ran the code below   and in the results, it does not show the labels but instead the original variable names. I'm sure its something really simple to fix, but it feel like I did everything correctly, but I dont know what else to do .   Thank you.   ... View more
