Action not executing

[BobG]

I have a Child table with a Ref to the Parent table. I have an action on the child table that executes properly. On the Parent table I have an action (Execute an action on a set of rows) referencing the action on the Child table that is not working. Both tables have a columns with the same log key referenced in the formula.I suspect the Referenced Rows formula is bad.

Select(Log[LogKey], ([LogKey] = [_THISROW].[LogKey]))

Any idea on why this is not working?
