Fly Height Trigger Help?

Animation - Change Unit Fly Height
Change (unit) fly height to (height) at (rate)

Now I do not understand what I put in for Rate...
I have this in a loop so it will create multiple units, and attempt to set their fly height..
However it will only change their orientation to each other (another part of the trigger)

It looks something like this:
Loop (8 Times)
-Loop (5 Times)
--Create 1 Flying Unit
--Move unit (instantly) to position
--"Animation - Change (last created unit)'s flying height to (variable for height) at --(rate?)"
--set (variable for height) = (variable for height) + 20

There are a few other things in there but that is what is relevant.

With rate the higher the rate the faster the unit will change hight, I usually use around 1000 but that might be too high for your neads.

Also make sure they are flying units, you cant change the flying hight of hovering units(or any other than flying) through triggers.

Rate is like Z axis speed a rate of 100 means that it will advance 100 each second. A rate of 0 means instantly

Actually while I was messing around with it, I solved my problem.
The Rate is how fast it changes, 0 is instant.
Although you need to have the order to change the flying height, THEN move the unit.
I did not know this :( So as you can see in my other post, I had it move them, then try to adjust height..
Something for us all to know in the future :D

(And yes they were all flying etc. etc.)
