		//Uncaught (in promise): Error: Type TicketsPage is part of the declarations of 2 modules: AppModule 
		// and TicketsPageModule! Please consider moving TicketsPage to a higher module that imports AppModule 
		//and TicketsPageModule. You can also create a new NgModule that exports and includes TicketsPage then 
		//import that NgModule in AppModule and TicketsPageModule.
