Yanfly Action Sequences I if condition

Hello,

Yanflys Action Sequence Pack 1 allows if statements

Usage Example:
    if $gameSwitches.value(1)
        action effect
    else if $gameSwitches.value(2)
        action effect
        action effect
    else
        action effect
        action effect
        action effect
    end

Which code do I need to ask if the target characters has a certain state.

So basically I want to ask if the target has state 12 (12 is the id)

What do I need to input?

I tried

if state12: target (I want to ask if the target is affected by state 12)

actions here

else

end

That would have been to easy, I don't anything about java script. A little bit help would be much appreciated. :p

Thank you anyways! :)
