title: I cannot reference a different Visio shape Master on the shapesheet
body: <p>I'm attempting to create a custom stencil, and one of the ways I want to make developing this easier is to have children reference the dimensions of parent stencils (parametric design).</p>
  <p>In the below pictures I'm showing the values I want to refer to on the parent, as well as confirming the Shape Name is <code>Shape.7</code>.</p>

  <p>But when I attempt to refer to it on the child shape, I'm told I have an invalid formula, even though the autocompletion in Visio is listing the available fields for me which appears to confirm I'm referencing it correctly:</p>

This is the stencil I used to create the screenshots above. I simply want the Child shape to inherit constant values from the Parent shape rather than copying them, so that modifying the parent would automatically update the child.</p>
