Sorry Mark one more question please!

Let me describe the steps that i have done.

1- I created the variable that i will use in the scheduler(Editor).
2- Then i created the switching point in the scheduler (Runtime).
3- Now what i want to do is to change the switch point (e.g. change the execution hour) in the scheduler without "touching" the scheduler element. I would like to do this with a VBA Script.
It´s possible? Could you tell me some more information please.
Thanks one more time.
