link parameters with slider so i can change them on runtime

can somebody help me please. tale a look at picture

Where is this component? Is it in a blueprint, an actor etc?

Its HoudiniAssetActor, that has parameters i want to link with sliders and move them on runtime

Basically you need to use GetAllActorsOfClass or GetAllActorsWithTag and hunt down the one which you have put in the map/level. But because the bind happens every tick you need to be economical with the GetAll call.

It’s hard to say much more without seeing what’s going on.
