Trouble with Navigation Toolbar Sample

[MatthewLawton]

I am trying to add the Navigation Toolbar sample to my application. Works great in Firefox, but in IE8 I keep getting the error "Object doesn't support this property or method" on the line that declares the navToolbar variable. Here is a code snippet showing the order I declare the map variable and the navToolbar variable:

  //Set the map variable and assign it to the mapDiv box   map = new esri.Map("mapDiv",{extent: initExtent, slider: true, nav: true });    //Define navigation toolbar - IN DEVELOPMENT   navToolbar = new esri.toolbars.Navigation(map);

Since it works fine in Firefox, I'm sure there is just some simple IE code issue that I am overlooking. Any suggestions are greatly appreciated.

Nevermind. It was a variable scope issue for IE. I had to declare navToolbar as a global variable outside of my startup function, even though it has no problem with all of the other global variables being defined this way. Go figure.
