In case anyone else encountered this problem. You have to edit your function and check the "has return value" box. Then your return will work. After this you have to use "Call Function" again and now you have a new field for saving results.
@Fox Thank you for this info.
I think it is the right place to ask how to do the reverse work.
I do mean i would like to set a variable to empty. I have the error message : Variable value is empty
Thanks a lot for the time
Edit : Oh my Bad sorry!
I forgot i ve seen previously in the forum that increasing variable with 0 was doing it!
So problem solved!

Initialise
Set Variable No-of-Cycle
For 1:No-of-Cycle
Call Function 1
Set Variable No-of-Times
For 1:No-of-Times
Call Function 2
Call Function 3
Increase Variable 1->No-of-Times
Sleep 30 minutes
Increase Variable 1->No-of-Cycles

During running of the cycle/times, how to clear cache?
