Hi @teodorsotirov welcome to the community!
Try to put the content of the line 15 between the brackets of the constructor.

construtor(activitySrvice: ActivityService){
      this.activityList = activityService.getAllActivites();
}

Be careful with the correct declaration and writing.

@TomCosta, thank you very much. It;s ok now.
