Help with Animation loops

I need to know how to get an animation to loop. The way i'm doing it right now is playing the attack animation, and have the trigger repeat itself (and it repeats forever, till the unit dies). Is there any way of doing it so that the animation will play until the unit given a move, or attack order?

So basicly: How do you get an animation to loop, and not be stuck playing the animation forever?

Maby giving it a dummy spell with the animations strings: attack and looping

im not sure i want a dumby spell... These animation loop triggers are included in DoB RP, so if you need to know what i'm talking about, take a look at that map.

While im at it, I might as well ask another question rather than start a new thread. Here it is:

How do you change max life or mana in game?

For example. Say we have a unit that has make life of 300. The player wants the unit's max life to be 500. So the player types something like "life 500" as an event, and then the action would set the unit's max HP to 500. I've tried using the "Unit - Set Unit's life to (NUMBER)", but it doesn't set the unit's life above it's max HP. This trigger IS possible, as it too is in DoB RP.
