Unable to resolve dependency [Parameter #0

#1

I get the following error message with the following code:
Unable to resolve dependency [Parameter #0 [ $name ]] in class App\Http\Livewire\AdvertismentStep2

public $name, $value;
public function updated($name, $value) {

            DB::table('advertisments')
                ->where('id', '=', 48)
                ->update([
                $name => $value,
            ]);

        }

                    <div>
                        <label for="brutto">{{ __('words.brutto') }} (EUR)</label>
                        <input class="form-control" id="brutto" wire:model.lazy="brutto" type="number" name="brutto" placeholder="{{ __('words.euro') }}" required="required"/>
                    </div>

what does that mean ?
