Hi, Just need a help on how to hide property if binding value is not passed and no visibility property available for elements. e.g. In Liner scale if i have created a 4 elements, HH,HI,LO,LL and bind an indiect parameters to it. On a page equipment only have a HH,HI and other equipment has HH and LL. So if i want to hide other elemnts without overlays/error how can i do it? ---

On the visible property, read the tag and use the `isGood` expression in a transform so that each thing hides if it’s not good quality ---

Thanks but in Linear Scale - elements there is no visible property on individual elements. ---

Hi nminchin, thanks and it works partially. I mean if tag is defined than its fine but when its not defined still it shows as overlay error unless i am doing it wrong. As shown below image, HH ( indiactor 0) and HI ( indiactor 1) is fine as tags defined through indirect binding but for LO ( indiactor 2) and LL ( indiactor 3) not passing any value and still it shows as overlay error in runtime for indicator 2 and 3 as Bad\_NotFound. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/1/1/11588f945bd7c7614ee369f6788d1c42e20adfd1.png) ---

Set the value bindings to opt out of overlays ---

If you want to show other qualities, then you’ll need to read the quality of the tag with `.quality`, convert it to a string with toStr and compare it to ‘Bad\_NotFound’. Set the value to the tag value when its not not found, and something else when it is not found as well as hiding jt, or similar
