Earth Shield rebuff issue


I am trying to include an Earth Shield rebuff in my DPS sequence.
Have tried including it in all possible ways.

I think this is what it should look like, but it is not working, I assume it is a formatting issue:

/castsequence reset=combat [@focus] Earth Shield, null

*should cast Earth Shield on focus (tank) once per pull (reset=combat)

Any advice will be appreciated!

think it needs to be the following way
/castsequence [@focus] reset=combat Earth Shield, null

Awesome, thank you! Works like a charm!
