Condition syntax?

For some reason the mindchip refuses to cooperate 

I want a trigger to fire, only when the actual favorite is different from the fav before the off.

- this is what I came up with:

....and selection trigger expression r_1_last_order is not equal to 1

Am I overlooking  something obvious or can this condition do the trick?

Thank you!

hi
yes you are correct.
BUT remember to tell the trigger what selection you want to bet on, by setting the trigger to favourite or using the condition  and selections rank is equal to 1
