I Need help with a pet battle turn counter.

[morish]

I'm trying to make a pet battle turn counter but I do not have much experience with lua/developing addons so I'm trying currently create this as a weak aura.

I'm trying to use the CHAT_MSG_PET_BATTLE_COMBAT_LOG event :
http://wowprogramming.com/docs/event...TLE_COMBAT_LOG

This event should return the pet battle combat log which should contain a line saying what turn it currently is:
"[05:35] [Pet Battle Combat]: Round 1"

This is what I have got so far:

and

When in a pet battle the aura only displays "1.#INF", from what I understand this seems to be returned when there's some sort of exception.

Any help/tips would be greatly appreciated.
