The operation Elements can't accept the arguments *empty-string*

Good evening friends I would like some help from you I have a problem with the code and I need a little help who can help me please


and that's the problem :point_up:

The Elements property of a list can't be compared to an empty string... why? because it is a list... syntactically correct would be to compare it to an empty list... the question however is, why do you like to do that comparison?
