Correct syntax for multiple execution lines inside an if-else Crystal Report formula

I keep getting an error "A string is required here" in my Crystal Report formula. The part that gets highlighted is the "else" portion, suggesting that is where the error is. I've tried so many different variations of brackets, no brackets, semi-colons, etc... sometimes I get a different error but none of it seems to work.

Local stringVar outputString := ""; 
if isNull({Evaluation.Strategic}) then
(
 outputString := "None"
)
else
 (
stringVar array x := split({Evaluation.Strategic},"|"); 
Local numberVar i;
For i:=1 to Count(x) do
   (
   outputString := outputString + x[i] + Chr(10)
   )
);
outputString;

Can anyone please point out to me the correct syntax to do what I want to do? All the samples I've found online (there are few with multiple lines inside the if-else blocks) suggest this should work.

Thanks
