SubModel does not exist



I am a beginner in ImagineLabs AMESim and am stuck. Hope somebody can quickly resolve my issue.

The issue is that I happened to create and compile a new sub-model of an orifice using AMESet. The variables has been modified so as to satisify my simulation requirements. The models couldn't be connected in AMESim and thus am stuck in Sketch part still. Attached photos of the components and external variables for reference.
