Question: I have a list in one file html called "filed1":

```
<ul> 
    <li>Nombre:<a class="boton" onclick=move() title="Caja">Caja</a><br> 
    <FONT SIZE=2>Fecha: 21/12/1994</font></font></li>
</ul>

```

Now I want to change a string in other html "filed2":

```
<a id="logo-header2">
    <h1>
        <span class="site-name" id="element">Details</span><br>
    </h1>
</a> 

```

Using Java Script:

```
function move() {
    mywindow = window.open("file2.html");
    mywindow.document.getElementById("element").innerHTML="Changed");
}

```

But there is an error which says that `mywindow.document.getElementById("element")` is NULL, why? The id element exists in the other window. Is there another way to change the string?

Answer: 
I was successfully able to configure and provision a new device using the following method:

1. Project properties
2. Debugging
3. Remote Computer Name, drop down and select Configure...

4. Successfully shows the device configuration wizard, and was able to provision the target computer.

Was then able to select the target in Driver Install - Deployment, however I get the following error when selecting "Deploy". This could be related to my project tho, please let me know if you also see this.

```
Please select a valid target machine for deployment from the project property page

```

**UPDATE:** the above error may have simply been that I had the wrong configuration selected when hitting Deploy.
Not really a fix, but I went back to Visual Studio 2013, as it does not have this bug, and driver dev is working great.
