Can someone tell me if this pseudocode for a case statement makes sense? ^^;

target num ← 3 case target num of
1: score ← score + 20
2: score ← score + 10
3: score ← score + 30
output score
end case

im trying to set 3 different targets and change the score by those values for each target that a ball collides with just wanted to know if i did something wrong or im using this case statement the wrong way ^^;
