How do I locate the tag that is causing my expression binding to fail?
Show your expression. (It may be a property, not a tag, and many such bindings deliver a null on startup before the binding system can deliver the proper value a bit later.)
The actual properties that have errors contributing to that error count are generally shown with a red background.
How do I show my expression? How do I view the actual properties to view the errors in the red background?
Scroll through that PROPS section of the Perspective property editor. You may have to expand objects and arrays if someone has set up deep bindings. When you find one, click on the chain link icon to its left to open the configured binding expression.
(Have you gone through the Inductive University free online training? These are basics that are covered by it.)
Yes I've watched some of the videos. I watched the video of how to setup expression binding. The expression binding for all of the tags i added (68) was working. This morning I'm getting the value:null and I don't know which tag is causing the issue.
I can't see your screen, sorry. You'll have to show more.

Got it resolved. Ignition was receiving bad quality on 2 tags. The expression binding for the 68 tags are now updating in perspective. Thanks for your help.
Ok will do and totally understand. Thanks.
