Animating/Looping in a BP

My blueprint is currently taking an instanced static mesh, creating multiple instances and controlling the location and rotation of each instance using csv data. The youtube video i watched to get this working setup the start of the eventgraph like below where pressing Y & T changes the state and it smoothly interpolates between the location & rotation states (this is currently working great)

Ideally I will want to have 10+ different location & rotation states to transition between and I want it to run on an automatic loop instead of needing to press buttons (Start > Transition from state A > B over 2s, B > C over 2s … Z>A over 2s and restart the process until turned off) - I’ve wrested with chatgpt & as many relevant tutorials as I could find to get this working but having no luck

Below is also the script making the transformation if that’s any help


Any and all help is really appreciated!
Cheers
