OK, so this is a new mesh? If so, you need to also create the morphs in whatever tool you used for modelling, then use Morph Loader to load them (making sure you use the right scale or your morph will have unintended effects). If you have the Advanced Figure Setup Tools then you can use Morph Loader Pro to load multiple morphs in one operation, otherwise the basic Morph Loader works one at a time. Both are in the Edit menu.
