Error : the function "if" must have 3 arguments but has 2

I got this error while doing the "generate attributes" for my sentiment analysis. The error is caused by this expression:

if(Score > 0, "positive", if(Score < 0, "negative", if(Score == 0, "neutral" )))

I hope that anyone can help me to solve this problem. Thank you very much

Hi @rosie you are missing the last part of the last if

if(Score > 0,

"positive",

if(Score < 0, "negative",

if(Score == 0, "neutral","" )))

What happens if the third if is false?
