React: Reaction to party member's weaponskill and/or skillchain not working

[ShoppyCodes]

It seems that any action from another player doesn't get recognised. Here's what I'm trying, please let me know if this is wrong as it would be very useful to be able to react to skillchains (or at least a party member's weaponskill).

["PartyMemberName"]={ ["Hexa Strike"]={ ["complete_reaction"]="input /pet 'Heavenly Strike' <bt>", ["ready_reaction"]="input /pet 'Heavenly Strike' <bt>" } }

I added the reaction in both ready and complete as it wasn't working and I figure at least one of them should have triggered the reaction.
