Can't rotate pawn vector

Premise : Sorry for my “google translator” english

Hi , i want to be able to move my pawn using his forward vector , so when the pawn rotate, his vector used for movement should rotate too.
This is the code , but i get error at this line :

CurrentVelocity.Rotation = FMath::Clamp(YawValue, -1.0f, 1.0f) * 100.0f;

saying " ‘=’ failed to function as left operand"

The Rotation controls work fine , as the movement along the X axis , but i can’t get that axis to rotate when i press the “rotate buttons”.
This is the code:
