My Character not compatible with float

ive been fallowing the tutorial for UMG inventory system, and in video 6 when setting up the blueprint for using an item to gain health, he connects the my character reference to to his set float. but when i try to do it, it says First person character reference not compatable with float… any ideas on why its doing this?

The “Set Subtract Energy” is from HeroinPickUp blueprint , not from My Character. if you want to modify something from ‘mycharacter’ , you need to have a variable “SubtracEnergy” in MyCharacter and call inside “HeroinPickup”, Is like you do with “EnergyValue” variable.
