Damnit I did it again - the solution was...

/cast [harm] [target=targettarget, harm][] Lightning Bolt
I don't think you need the []

Code:
/cast [harm][target=targettarget, harm] Lightning Bolt
should work.

The [] is just an empty condition and you can't cast lightning bolt on friendly targets anyway. So using [harm] and [] is superfluous.
