How to Import Editor Window Variables to a Script?

The problem is I need to get variables from an editor window to a script. Here’s my code for the editor:

class TestEditor extends EditorWindow {
	var myValue : float = 2.0;

	@MenuItem ("Window/Test Window")

	static function Init () {
		var window : TestEditor = EditorWindow.GetWindow(TestEditor);
	}

	function OnGUI () {
		GUILayout.Label("Test Editor", EditorStyles.boldLabel);
			myValue = EditorGUILayout.FloatField("Translate Z", myValue);
	}
}

And for the script:

private var testEditor : TestEditor;

function Awake () {
	testEditor = GetComponent(TestEditor);
}

function Update () {
	transform.Translate(0, 0, testEditor.myValue * Time.deltaTime);
}

But I get an error:
