variables in Script task VS Script Component

[joe69008]

Hi,

How do I reference and modify package scope variables in a script
component (within a data flow task)? I tried copying the syntax I used
in a Script task, but got a "Dts" not declared:

Dts.Variables("User::MESSAGE_ERREUR").Value = ...

Above works in Control flow Script task, but not within a Data Flow
Script component.

I'm simply trying to affect an error message to a variable.
And after, how can i do to read this message_error variable?
Do i use a script component to?

Thank you
