The result of any mathematical operation on a missing value results in an answer of missing hence your result.

 

If you want the average of the non-missing values use the mean function detailed here http://support.sas.com/documentation/cdl/en/lefunctionsref/69762/HTML/default/viewer.htm#p0vl2htnkjk...
