I try to run a Fleiss Kappa Analysis on two nominal variables (each variable represents the rating of 1 rater) but I get the error message [errLevel 63] Submit cannot be used from within a User Procedure or while there is a Cursor instance.

Don't know what is the issue and how to fix it

I presume that you are using the extension command, not the new V27 Fleiss Kappa procedure.

I suspect that you ran a procedure that failed and left a case cursor open. If so, restarting Statistics should clear it up.

Thanks for your answer!! Yes I have V25 so I downloaded the FLEISS KAPPA extension.

I tried to restart several times but it still does not work. I tried it also with different sets of variables and on a different laptop also, but I receive the same message.
