Can set sequence properties but cannot play sequence actor using C++

Hi everyone,
I am just learning Unreal for serveral days! I had a bug and tried to search but I cannot get the answer, maybe i was using wrong keywords… due to lack of experience.


The bug is that I use code to setup successfully the Sequence (Animation ?) properties: AutoPlay, PlayRate and Loop so that animates the BP_Cook (simply scaling up/down), but it just played once.
Can anyone help me with the code that correctly play the animation?
