[How to split a pinned section into multiple ScrollTriggers]

Hi,

first of all I thank you for taking the time to read my question and sorry for my english, I hope you understand me.

 

I am trying to do the following:

I have a pinned section and I need to split it in four equals scrollTriggers.  So when I scroll down the pinned section, I get four alerts, one for each subsection.

 

Thanks for the help and advice.
