Hi, could you create a sample capx to show the problem?
edit: never mind, have a look and see if this is close to what you want. I notice you are comparing absolute Y values which will not often match up exactly.. Here I'm just using an offset of 10 above and 10 below.

(I'm just setting a textbox with the picked count of each floor).
