Thoughts on how to create linked sliders that control a variable

Hello again …

I did part of these steps already, 1st step removed all that part, 2nd,3rd,4th,5th done.
At 6th step …Should i create function by bind at slider value ?? and the return value will be my SliderVal (float variable) ??
At 7th step … you telling me to set the morph target inside my character blueprint, but my character is just a static camera and have no mesh or morph targets … its an object in the scene that have the mesh and morph targets. So i set 7th step in my object blueprint or still in my character blueprint ??

Your videos helped me on how to create these functions. Thanks.
