I need to do math to an indirect tag

I am indirectly referencing some data through an indirect tag tied to a dropdown. My issue is that my data is in milliseconds and I need to divide by 1000 to get seconds. I can do that through an expression, but I can’t figure out how to do an indirect tag and an expression at the same time.

Use the tag() function to construct your indirect tag reference, then do your math.

That did it!
