Hi @Alex_Stefanacci - this can be done with a lookup and a formula. In your tasks table you’ve got something like this:

In your Initiatives table you can lookup all of the current states of the tasks associated with each initiative:

The “initiative state” field is a formula which shows the “summary state”:
IF(
OR(
FIND('Backlog', State & ''),
FIND('In progress', State & '')
),
'Not Complete',
'Complete'
)
However, beware the task with no state as this will give you a false initiative state:

You might want to put an alert column on a task with no state as a reminder to set it to something.

A couple of other comments:
- you can’t just check for the presence of state before you do the
IF()
formula as there might be a number of tasks and all but one of them have a “complete” state, the other task having no state at all, so this would still give an incorrect result.
- In the formula State is stringified using concatenation:
State & ''
This is done as the State Lookup is an array and you cannot do a FIND()
on array - it must be a string.
Here’s a variation on @JonathanBowen’s suggestion. In the oTasks]
table, I added a formula field that displays an X if the state is anything except “Complete”. This includes tasks with no state chosen.

In the eInitiatives]
table, I roll up that {Marker}
field instead of the states, using ARRAYJOIN(values, "")
to pack everything together. My formula for the {Initiative State}
becomes fairly short:
IF(Markers & "", "Not Complete", "Complete")

Thank you both for your suggestions. Very much appreciated!
