I’m inicando with fusetools, I started doing the tutorial of your page when I get to the part of:

[https://www.fusetools.com/docs/tutorial/navigation-and-routing](https://www.fusetools.com/docs/tutorial/navigation-and-routing)

Page ux: Class = “HomePage”  
Router ux: Dependency = “router” /

"  
when I add the dependency, it gives me the following error.

## ‘HomePage’ must specify required attribute ‘router’

Errors Were Encountered while building the project

I would appreciate any help.

Hi!

Looks like the error is telling you that the `router` attribute is not set.

If you are following the hikr tutorial I suspect that you have done something like this:

```auto
<Page ux:Class="HomePage">
    <Router ux:Dependency="router" />

```

Now `HomePage` cannot be instantiated without its dependency [(dependency injection)](https://en.wikipedia.org/wiki/Dependency_injection). So you need a `<Router />` in scope and pass it to the `HomePage`.

For example:

```auto
<Router ux:Name="router" />
<HomePage router="router" />

```
