A 3d model is basically made up of points in space, the lines that connect those points, and faces that give the model surface. 'Vertices' are the 'points' of the model. Morph targets in Poser only work on the models they were made for. They require that the model they are applied to has the same number of vertices recorded in the same order in order to function properly. If you have a brand new figure, you need to make brand new morph targets for it. These can be done using the magnets in Poser or externally in a 3d modelling program. Hope this helps.
