isValid layer?

[bagonterman]

  var myEmboss = app.activeDocument.layers[0].layerColor; ///gives a number

       var myEmboss = app.activeDocument.layers[0].isValid; ////is undefined/?

So this should evaluate to true but I get undefined. Why?

[Benreyn]

isValid is a boolean check.

if(app.activeDocument.layers[0].isValid) {

           $.writeln('T');

}

It seems to be working.

so on it's own I tried it and it worked. I now know it is a local problem. Inside my script.
