Hi,

I developed Ecommerce app.

If the user orders the products Need to [authenticated.So](http://authenticated.So) going to SigninPage.

I passed the query params in nav.push.user after signin.

Here is my code

```auto
this.navCtrl.push('CustomershippingPage',{Page:'Signin'});

```

.  
Going to `CustomershippingPage`.

If user go to back click **nav backbutton**.

I Check the query params value is Signin and page is pop to `cartPage`

Here is my code.

```auto
        if(this.Page == 'Signin')
  	 {
  	    this.navCtrl.popToRoot('CartPage');	
  	 }

```

But it does not work.The page is pop to Signinpage.why?

Kindly advice me,

Thanks.
