Specifying animations

I just wanna know how I can set certain animations to only show for certain occasions.

ie: I have 3 attack - alternate animations on a model and I want them only to work on an alternate unit (i know i have to add the -alternate tag to work on the alternate unit but it works on the regular unit when it shouldn't). Right now they work on the unit regularly like any other attack. Is there a special tag i need to add on or a certain word to type with them (right now i have it like the following: "Attack - Alternate" for the animation name, but it still plays on the normal unit....), or is it something else? Thanks in advance, hope this makes sense...

A dash in a sequence name makes everything afterwards a comment.

You need Attack Alternate, not Attack - Alternate.
