			helpString = "Number of objects selected: " + Selection.objects.Length;
	}


	/// <summary>
	/// Rename
	/// </summary>
	void OnWizardCreate() {

		// If selection is empty, then exit
		if (Selection.objects == null)
			return;

		// Current Increment
		int PostFix = StartNumber;

		// Cycle and rename
		foreach(Object O in Selection.objects) {
			O.name = BaseName + PostFix;
			PostFix += Increment;
		}
	}
}

works like a charm, thanks!
