Why the event sheet1 does not work on event sheet 2?

Event Sheet 1 Layout 1:

Mouse X=100 --> Add to jump 10 (jump is a global veriable)

Event Sheet 2 Layout 2: Here is the Caracter

And the jump belongs to caracter.

It does not work.

How to solve this?

You can only assign one event sheet to the layout, however you can 'include' other event sheets which is what you need to do here. Right-click on event sheet 2 and include event sheet 1.

Thank you!
