How can I debug SSE value during run Neural Net model of each loop in Rapid Miner

Hello,

I'm student and interested to use Rapid miner run Neural Network Model to come out the formula to predict the defect using in HDD factory. I've run NN and comeout both prediction model and their accuracy using x-validation. But, I also would like to get the SSE (sum of square error) of each loop for debug more information. Any possible way to get SSE of training cycle? In this case, I set maximum 500 training cycle. Need your help. It is very critical for me..

Here are my setting picture.
