I am attempting to add a Scrubber System to an existing Ignition project. I am using the same screen, but changing the tag values based on the site location.

The previous Engineer some how used a [.] to represent the tag path in the Expression Editor? I need to add the same tags, but change the path. How can I change the value of the [.]?

From the docs, at least when used on a tag:

[.] Relative to the folder of the Tag that is being bound. This is especially useful in UDT definitions.

I'd expect that all they did was to use the tag selector to choose the tags, and it added in the relative tag reference automatically
