Noob macro question about channeled spells

So i’m trying to mess around with the macros and am not having much luck with the one im wanting to create. I’m using a WW Monk and basically want to cast Crackling Jade Lightning x3 then case Effuse once then repeat the process. the part im having trouble with is the the lightning is skipping cause im not sure how to make it so it wont skip channeled spells. Any help would be awesome.

How does your macro look like atm?

I have tried
Sequences[‘taco’] = {
author=“Chuye@Dentarg”,
specID=10,
helpTxt = “Talents: 2320000”,
icon=606542,
lang=“enUS”,
PreMacro=[[
/targetenemy [noharm,dead]
]],
"/castsequence [nochanneling] reset=target Crackling Jade Lighting, Crackling Jade Lighting, Effuse, ",
PostMacro=[[
/use [combat]14
]],
}

and without /castsequence and just doing /cast for each one.
