question for a kick maccro {help]

hey how can i get that same maccro for focus ?
/cast [equipped:Shields, stance:1/2] Shield Bash; [noequipped:Shields, stance:1/2] Berserker Stance; Pummel
this maccro cast shield bash if i have a shield on me and if not switch to berserk stance to cast pummel right?

so what is the difference with:
#showtooltip Shield Bash
/cancelaura Hand of Protection
/cancelaura Bladestorm
/cast [stance:3] Pummel; [stance:1/2,equipped:shield] Shield Bash
/stopmacro [stance:3]
/equipslot 16 Wrathful Gladiator's Cleaver
/equipslot 17 Wrathful Gladiator's Shield Wall
