@gglick This is working! seems like “Filter Variable ‘Variable’ with Value of Named Variable” is a must. ▼
I've searched the forum and got this: What does "Filter Variable ‘Variable’ with Value of Named Variable" do? - Questions & Suggestions - Keyboard Maestro Discourse_2019-07-08
Still a little confused though but I'll try to digest it...
Anyway, Problem solved! Hooray~
@ccstone Thanks for the solution!
@gglick Thank you too for the explanation.
