Hey Guys,

I’ve been struggling the past couple of days trying to figure out the navigator, router and flow of data. Right now I’m running into a weird problem trying to pass an argument through as a parameter as I instantiate a new page with the navigator. Feels like I’m just doing something weird, but I can’t figure it out.

Instead of the argument coming through in this.Parameter, it appears to be coming through in something called “raw parameter” that isn’t documented anywhere that I could easily find.

My function called with a Click="{goToDetails}". Upon debugging the argument here has my data that I want to pass through.  
![file]([https://s3.us-east-2.amazonaws.com/fuse-legacy-forum-assets/0Enq9PsrpcSV-image-1473929020854.35.28](https://s3.us-east-2.amazonaws.com/fuse-legacy-forum-assets/0Enq9PsrpcSV-image-1473929020854.35.28) AM.png)

Then upon instantiating the new page, this.Parameter is empty while \_raw\_parameter has the data that I wanted to pass through.  
![file]([https://s3.us-east-2.amazonaws.com/fuse-legacy-forum-assets/ozTjkYFdCU3L-image-1473929163566.36.29](https://s3.us-east-2.amazonaws.com/fuse-legacy-forum-assets/ozTjkYFdCU3L-image-1473929163566.36.29) AM.png)

Any ideas on what I’m doing wrong?

Hi! Sorry about the slow reply.

This is probably not the cause of your issue, but i believe you want to pass `arg.data` to your router, not just `arg`. Could you see if this makes a difference?

You have to keep in mind that the passing of a parameter argument happens asynchronous from the actual evaluation of the javascript module. `this.Parameter` is an Observable (you can read up on that here: [https://www.fusetools.com/docs/fusejs/observable](https://www.fusetools.com/docs/fusejs/observable)), and so you have to actually subscribe as a listener on it in order to be notified of when its value actually changes.

Try doing something like:

```auto
this.Parameter.onValueChanged(function(newParam){
    //here we have our new parameter
});

```

to get a callback when the parameter changes.

I hope this helps 🙂
