Putting animations back

When i export the model , he doesn't have animations.So how i put hes animations back?

More details, plz saying of what you did and what model you exported by using what exporter*

Oh sorry ! I edit the model with 3dsmax , and when i exported the model doesen't have animations.

ehm what exporter you used?

I used the MDX Importer/Exporter 2.0 (impexpmdx.mse) , and i read Oinkerwinkle tutorial about Geoset merging.
In tutorial looks like this:
==========================================================
3) Combining the models
Convert the following four files to MDL: Skeleton.mdx, Peasant.mdx, Skeleton_chunks.mdx, Peasant_chunks.mdx.

Editing the peasant to be headless
Open the Peasant.mdx and Peasant_chunks.mdx. Peasant_chunks.mdx contains all the vertex information you need, but Peasant.mdx contains all the essential animations as so on. You have to copy the vertex animation from one to the other. In Peasant_chunks, search for "Geoset" (no quotes). You should find an area like this:

Code:
Geoset {
Vertices 302 {
{ 2.84348, 0.0383234, 74.9834 },
{ 2.84347, 0.0383427, 74.9835 },
{ 2.84344, 0.0383686, 74.9834 },
{ -6.64947, 7.36909, 27.8454 },
{ 1.56159, 13.7381, 35.8622 },
{ 0.86169, 12.2178, 29.2713 },
{ 8.90468, 6.93236, 27.4755 },
{ 10.265, 6.63715, 36.1995 },
{ -3.69442, 0.34387, 32.9351 },
{ -10.9366, -0.62374, 44.2371 },
......(lots more).......
{ 15.5051, 2.94313, 0.008 },
{ -9.65277, 15.4167, -0.0337 },
{ 11.5467, 17.3316, 0.20145 },
{ 1.01264, 16.2429, 8.70893 },
{ 6.97408, 9.91933, 9.11298 },
}
It continues like that. Copy starting from behind Vertices 302 to the line with the line "}".
Now, in Peasant.mdx, search for Vertices 302. Select the area from there (Vertices 302) to when it closes (the lone "{"). Paste what you copied over it. You have now replaces the vertex information. If you where to convert this file to MDX and view it, it should be a headless peasant.
==========================================================
My problem comes now:
I edited my model( a warden base model) i exported my model ,i converted to mdl. So i have my model and the original warden both converted in mdl.
And i opened them , and what should i have to copy to put warden's animations to my warden edited by me.Be very specific with me pls i am getting tired of this.
Sorry for the long post.........but i had to explain

It is so you can just edit the geosets and that stuff, then you have to manually copy the geosets and vertices from the new one to the original one so it keeps the animations

Whell thank you.. i will try to copy and i will tell the results

Whell i tried ... i copied the geoset verticies after i copy the model becomes how it was like i didn't edit him........... :(

hmm you surelly pasted wrong vertix data. be sure that you pasted the vertex data of the edited file on the original one.
