Ask and wait to select a plane with macros

Hi.

I have created many macros, but I am having some dificulty with a simple easy task.

I want to create a sketch in user choosen plane.

I know I could do it on a pre-defined plane, but I need to be able to choose it.

This isnt enough:

Set Part = swApp.ActiveDoc

Part.SketchManager.InsertSketch True

boolstatus = Part.Extension.SelectByID2("Right Plane", "PLANE", 0, 1, 1, False, 0, Nothing, 0)

Part.ClearSelection2 True

any ideas?

Thanks!
