(sorry i'm not good in english)

I want to make morph with blender how it export?

and when I import my mesh to milkshape, morph export not work
the popup said
Face list of base group must match the morph face list

and autonum not work too

a morph is always a duplicate of the original mesh, they must stay identical(same ammount of faces and vertices)
You can export a morph as obj file or the same way as the base mesh.

When in Milkshape you always import the basemesh first, then the morph
Keep in mind that the base mesh and the morph use diffrent meshcomments
If you have fixed the mesh comments you can use the autonumtool and export both meshes as seperates, one as basemesh and one as its morph

I will try to import original geom file to blender and export to obj to milkshape
same with morph mesh

no, not export the original as obj file, you will lose the boneassignements

I imported geom and morph obj to milkshape
but can't export'
the popup said
Face list of base group must match the morph face list

how to fix this

Did the autonumtool work on them?
If not, then the meshes are not the same.
You can check both meshes in Tools/SelPolcount

both meshes have same group polygons
autonum did not work,pop up:Face 1 Point 1 does not match the base index 3
