Could not find predictor

After creating a predictor I tried to make a ranking system with the predictor, but I get a fault message- “ Could not find predictor”

What can be wrong?

There was a leading space in the name which the parser strips out, causing this error. I removed the space from the name of the factor for you. Try running it again after removing the leading space from the AIFactor().

Thanks, that worked. I got the formula from the copy button
