Hi I am trying to bind a boolean cell in a table in Vision to a boolean tag in **Ignition-Edge** but it is not working because it cannot coerce to a number? ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/b/9/b9734d8737ddd47b5354932d506bd5432a495932.png) ---

Edge isn’t relevant. The issue is that the value field of cell update bindings isn’t able to perform an ‘indirect’ lookup like you have there; you must use additional custom properties (referenced within your cell update binding, each with their own indirect tag binding) to accomplish this. ---
