[ari2495]

Hi, i need to count the number of observation that meets 2 conditions: i need to count the observations if column a is valued x and column b is valued y. Can you help?

[PaigeMiller]

if a='x' and b='y' then count+1;

Is that what you want?

[ari2495]

yes but I need a total sum

That is the number in the last observation.

Or you can use PROC FREQ.

by using proc freq statement , you count the no of observation
