Anyone can explain how I am getting this error? Thanks in advance :slight_smile:

Hi @lmoham

what is the output the tester activity?
Normally this error indicates when you have not initiated a DataTabel or Collection.

new List(of String)

Hi thanks for your response, here’s the tester activity

top thanks.
did you also initiate the DT variable “testsheet” somewhere or fill it with data?

Yep I did

Okay. I can’t explain it to myself.

I’ve recreated here a small series of pictures and I get no error.



Sorry! I can’t Rebuild the Error

Thanks for trying to replicate the error, it must mean the errors are from elsewhere thanks a lot :slight_smile:
