Why my random forest regression scorer node shows accuracy rate as negative big number?

Hi all,
Why my random forest regression scorer node shows accuracy rate as negative big number? I really dont know what is wrong although regression tree results shows well.

thanks in advance. I appreciate if someone knows it.

Hi,
Can you share a screenshot of the scorer node view? Would be good to see the other numbers and the confusion matrix.
Kind regards,
Alexander

Thanks for your quick reply. I guess I solved by chance. I used prediction coveraince instead of prediction itself. So I corrected it. Thanks alot.
