Formula box skill woes

[kaukusaki]

Im trying to figure out how to make a mp draining skill heal hp instead by using just the formula box. I'm probably over thinking it and after a week i can't get it working.
Am i overlooking something?

@bgillisp oops! ≥﹏≤
I'm on mobile and it's hard to tell at times.

a is the skill user, b is the skill target.
and then just use mp and hp as the attributes.

Example:

r=4*a.atk-2*b.def; a.hp+=r; r

(this is untested and would have some quirks if the target has less than r MP and so on, but you can take it from there)
