Hi Mounkara,

The missing values represent any value so the outcome is always missing. If you recode it to zero, you can sum it.

*sample data.
data list / x1 1-1 x2 3-3 x3 5-5. 
begin data 
1 4 8 
1 
1 6 
1   8 
end data. 
 
*actual code.
recode x1 to x3 (sysmis = 0) (else = copy) into #y1 to #y3. 
compute revtot = #y1 + #y2 + #y3.
* or alternatively:.
compute mysum = sum (x1 to x3). 
exe.
