Hi, everybody  
I have a message error that pop and various interval on my page

 ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/a/0/a0e4fbe25e94f0dffbba1e7a96597b65259e3a05.png)  
however, when i try to locate the custom-function, "IfAdditiveIsInfo" I can't find any  
place with that function. I've try to find it with the "ctrl-f" tool (Alltemplate, all... ), no mention anywhere.  
I've try to manually go through "IndirectsTags" objects but i couldn't find anyscript.

What are my options ?What are my other options to identify this issue.  
Thank you.

PS : here is the full message

The component name "IndirectsTags" is right in your first screenshot. Find that. Look at its `propertyChange` event.

`ifAdditiveIsInfo`, called from a property change script, is failing to find a `system.opc` function or function(s). The fact that you're on 8.1.0 and I haven't heard of anything like this happening anytime recently suggests it might be a bug we've already resolved; I'd suggest updating to the latest 8.1.X as a first step.
