How to Set and Transfer Variable Values from HUD to Third PersCharacter?on

What do I have to put for object in the cast to third person character?

I am making a character selection screen and i don’t know how to transfer a variable value (third person character variable) from the HUD to the Third Person Character Blueprint.

The third person character is not controlled by player though because I am using a different character so the character cant move. Will this affect what i put in as the “Cast to ThirdPersonCharacter” object?

I added a picture of my blueprint.

Can anyone help me figure it out?

Thanks
