Sorry my bad, I was trying to call the tween with the tag.. "DashboardUP"
I see
Normally, for this type of situation, the only way anyone can help you is by posting a minimal example so they can investigate it and show you what was wrong as it's hard to debug without seeing your project. They will just guess.
Here are some ideas you can test:
1-Make sure that the Tween "MoveToCentre" finished is triggering by adding a console log as you did on your second trigger
2-If the above tween Trigger is working then I will run the project on debug mode and check if that "PlayerBase_Collisions......" Boolean "isBasegrab" is = True
3-Then If the above two are true, I will run the project on debug mode again and check if the object "PlatformWindow.........." Exist on the current layout
4-Then If the above three are true, I will check that both Names (Trigger & Tween Action) match "DashboardUP" without any extra spaces
5-Then If all above are true I will post a small example reproducing the problem
