Just wondering how i can refer indirect tag to a property or path in another root or windows…simply i need to have one site name which will change all tags in all windows not only one.

I’m having a bit of a hard time understanding what exactly you’re looking for but I’ll give it a go:

You can use an expression binding like

```auto
tag(tagPath)

```

where tagPath is the path to your tag.

If I’m understanding correctly, you have bound data being displayed across your project whose binding changes depending on the site that the user selects? Something like: siteA/pump1 vs siteB/pump1

You could store the selected site in a client scoped string tag. Then in each one of your data bindings you can insert the selected site tag into the path.
