This error happens on two of my views and it happens sporadically, the binding will persist to being null even when the propertybinding value changes but the binding preview will not error out. Any ideas on why a system.date.now() would error out like this ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/3/6/3619da19db415f70e4b81a0ca34d1dcbb1454ce5.png) ---

What's going on over yonder? That's 'None' right? ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/6/5/6567bb7a9f2dc1850309581e7fcb3474392df4d5.png) ---

Not sure why that is giving you a problem, but why not use the timestamp that's already given to you in the transform? ---

Correct that is None, but i dont believe that is causing the error as i have the same error on another screen where the line that errors is strictly: now = system.date.now() ---

Your transform could be simplified to just this also: ```python return value > system.date.now() and self.view.custom.newStatus != None ``` ---

You could also replace this with an expression binding: ```python view.custom.dateTimePickerValues.selectedDateTime > now() && self.view.custom.newStatus != null ``` ---

When it's giving you the error, what is the selectedDateTime value? Is it null and maybe just giving a misleading error? ---

Yeah I switched it to a **from datetime import datetime today = datetime.now()** and i cant replicate the error again but i mainly was concerned about the date.now because ive used it a lot in the past and was worried if this would continue to popup errors ---

I would use the expression, but if you want the transform you already have a timestamp provided. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/7/7/77d36f894aa7e326c0050ff37d4100e51b3b7034.png) ```python if value > timestamp and ...: return True ``` ---

I was just correcting what he was already using so it would be clear. 🤷‍♂️
