            var form = document.forms.cvapplication;
			var output = '<p>Your submission has been accepted</p>';
            output += '<p>interests: ' + form.interests.value + '</p>';
            output += '<p>state: ' + + '</p>';
            form.innerHTML = output;

Dani, you nailed it first try.

I had thought about a creating a Object array to consolidate all statements,But then again wasn't really sure bout the function.., but they way you did it I have never seen it before, and I can see why you did it too, so the statements are a lot shorter...
I see what you did there my friend, very clever

By the way is it just me or it seems connecting XAML to C# or PowerShell is much easier as opposed creating JS..., I guess I'm making a big deal... hey on my defense this is my 3rd day where i'm connecting the 3 JS,CSS,and HTML... :)

Thanks so much!
