Hi folks
I'm new to SSIS so apologies for the newbie question. I've been following this guide -
https://www.simple-talk.com/sql/ssis/sql-server-2008-ssis-data-profiling-task/
For some reason, I'm not able to modify the second data profiler node so that the expression includes @Results == 'false'
I get the following error - The variable "Results" was not found in the Variables collection. The variable might not exist in the correct scope.
What am i missing, doing wrong/ any help /advice will be highly appreciated
thank you

Maybe you just need to add a variable @Results with the right data type.

@Ikuba thanks for your response. Considering my code is in the main class, where would I include this variable and how?
Thank you.

Did you add the variable to the Read or ReadWrite variables property of the script task?

The absence of consumable DDL, sample data and desired results is, however, evidence of the absence of my response

Right click in the Designer Window, Variables. On the bottom, in the Variables window, add a variable. Name it Results with String Data Type. Then you need to add this variable in the task (script task). Read or write, whatever your needs. Then you can use this variable in the script.
