Also, you can't have an Attributes nor TitleBar block for a child window. Directly quoted from the documentation (see Window/ChildTmpl):
quote:
annotation: A window with this template must not have Attributes or TitleBar. It is only meant to be included in other windows.
Another remark: you're defining the width and height of the window as absolute values (in pixels) using IsAbsolute, however you don't use Control::Position::Units to make the controls use pixels. This causes them to work with dialog units which are about 1.5 pixels, making your controls much wider/higher and positioned too low/far than you want. As always: all these things are clearly mentioned in the documentation.
