Need help with custom health bars

[Wietlol]

I was looking for a nice way to show health bars and someone recommended the Progressbar V2 by JesusHipster

I have seen that model being used in Tides of Blood as a bar with a custom mana type thingy and so it is possible to do it without having problems.

Now here is the problem:
I cannot find out how to use it on an easy way.
All examples and guides are for casting bars and they automatically set the percentage of how much is filled.

Can someone give me a good example of how I can use this in my map?
(I will only have a few units that will get these custom health bars so I am not afraid of lagg.)

Have you tried the map?

I would have but my editor cannot run the map and gives this compiler error: "libraries cannot require scopes"

EDIT: I also want a secondary bar that represents mana.
It must be slightly lower than the health bar ofcourse and preferably with a very precise offset.

Yeah you need Jass newgen for it to work, just click the "download" link in the thread.

I got a working vJASS but it still gives me that error
