How to put sys_properties to script include then call it in Business rule?

[Summer]

Hi! Can you guys help me with this one?? 

My requirement is to transfer the variables (sys_properties) in Script Include then just call it in Business rule.

Note: the sys_property has the sys_id of the email notification

What I did was I created a script include

Then I tried to call it in Business Rule:

RESULT: 

It seems that it is not getting the sys_id of the email notification because it is showing "empty here"
