Hi @begumkaplan -
Sorry for the delay - I was on vacation and am just now getting completely caught up with forum items again.
I think it would be best if you can post the current version of your workflow. The screenshot above indicates some type of syntax error in the expression inside the String Manipulation node, but the error is blocking the expression itself so I’m not sure what the problem is.
As to your second question, again I would have to see your workflow. It’s possible that you just need to join your predictions back to the text by some type of common ID, but it’s hard to guess without more info.
Please post your latest workflow and data and I will take a look.
