Assuming that Isaac is correct and the variables are indeed coded as 0
and 1, the -gen- command in his message only yields the sum of
selected responses if there are no missing values across the response
variables. With -egen rowtotal- missing values are treated as 0.

. egen newvar = rowtotal(vara varb varc vard vare)
