Need help with setting a variable in the level blueprint

Hello, I am currently experiencing some issues with setting a boolean to be true via the level blueprint.

The above is what I currently have, and I am not sure what the target should be in this instance. The “IsDay” boolean is set in the character blueprint, and has been set to public.

Get PlayerPawn > cast to “your player blueprint” > as that player blueprint, set your variable.

Watch tutorials on blueprint communication.

Thanks, I managed to solve my issue in a different manner, however this advice has been noted, cheers.
