Nostalrius Begins - Quality wow vanilla realm (1.12)

I have a macro for unbuffing myself from all forms.

/unbuff dire bear form
/unbuff cat form
/unbuff travel form

I wish to add to that, my mount. If I am mounted, it will dismount me.

I tried
/script if buffed("Teal Kodo") then RunLine(".dismount") end

but no luck. Any suggestions?

(I have supermacro and yes, i am a druid)

/unbuff Teal Kodo worked!
