Error When Importing Entry Components

Hi Treehouse friends! I'm really stuck on a console error thrown when I try to import the EntryList component into app.module. The app attempts to import infinite instances of the component, and the console throws this error:

(unknown) EXCEPTION: Error in ./EntryListComponent class EntryListComponent - inline template:2:0 caused by: Maximum call stack size exceeded

Been trying to debug for over an hour, finally gave up and rewatched the video making sure to copy Andrew's code line-by-line, and still can't find the problem. Any help much appreciated!

App.module.ts:

import {NgModule} from '@angular/core';
import {BrowserModule} from '@angular/platform-browser';
import {AppComponent} from './app.component';
import {EntryListComponent} from './entries';

@NgModule({
    imports: [BrowserModule],
    declarations: [AppComponent, EntryListComponent],
    bootstrap: [AppComponent]
})
export class AppModule{

}

Index.ts:

export * from './entry-list/entry-list.component';
export * from './entry/entry.component';

App.component.html:

<app-entry-list></app-entry-list>

Entry-list.component.ts:

import {Component} from '@angular/core';

@Component({
    selector: 'app-entry-list',
    templateUrl: 'entry-list.component.html',
    styleUrls: ['entry-list.component.css']
})

export class EntryListComponent {

}

Entry-list.component.html:

Hello From Entry List Component HTML
<app-entry-list></app-entry-list>

Problem solved:

I had two <app-entry-list> tags, one in app.component.html, and one in entry-list.component.html. Obviously the referenced tag should only be in app.component.html, because that's the only component that the application bootstraps. Wow, what a headache for such an obvious mistake.

what may have been the problem was where you have

import {EntryListComponent} from './entries';

should be 

import { EntryListComponent, EntryComponent } from './entries';
