[iscripting (I think)] 1 frame to 11 frames

[Church]

I have downloaded a .grp file off of Maplantis, and it has 11 frames. Frame 0 is just the idle frame, but frames 1 to 10 are building animations. I want to replace the Stasis Cell animation with this, but I don't know how. Do I need to iscript or something else? If it's important, I can upload the grp I'm replacing it with, but I don't think I need to. I have never iscripted before, and I don't know how.

I think thats it, if more details are needed I will give them as best I can.
