Demonology Macro Help

I'm trying to make a 2 button macro for Hand of Gul'Dan. I'm not sure what I'm doing wrong. Here's what I have:

#showtooltip Hand of Gul'Dan
/console Sound_EnableSFX 0
/petattack
/cast [nomod, button:1] Hand of Gul'Dan
/cast [nomod, button:2] Hand of Gul'Dan
/cast Metamorphosis
/script UIErrorsFrame:Clear()
/console Sound_EnableSFX 1

The idea I have is button 1 will cast Hand of Gul'Dan normally. Button 2 will cast Hand of Gul'Dan and immediately pop into Meta.

For some reason when I press button 1, it casts HoGD, then pops into meta. Am I missing another line of code between button 1 and 2?

#showtooltip Hand of Gul'Dan
/console Sound_EnableSFX 0
/petattack
/cast Hand of Gul'Dan
/cast [button:2] Metamorphosis
/script UIErrorsFrame:Clear()
/console Sound_EnableSFX 1

HoG is casted every time, the conditional should be on meta instead

That works perfectly. Thank you!
