CR IX R2: SQL Expression Editor - Max on Group

Question

This works, but it only shows the MAX value of the entire column, for all teams:
(SELECT MAX("PlanSegment_Team"."priority")
FROM   (("Plan" INNER JOIN "PlanSegment"
ON "Plan"."pkPlan"="PlanSegment"."fkPlan") INNER JOIN "PlanSegment_Team" "PlanSegment_Team"
ON "PlanSegment"."pkPlanSegment"="PlanSegment_Team"."fkPlanSegment") INNER JOIN "Team"
ON "PlanSegment_Team"."fkTeam"="Team"."pkTeam"
But I want to show the MAX value for each Team's list of priorities. The following is my best guess:
(SELECT MAX("PlanSegment_Team"."priority"), "PlanSegment_Team"."fkTeam"
FROM   (("Plan" INNER JOIN "PlanSegment"
ON "Plan"."pkPlan"="PlanSegment"."fkPlan") INNER JOIN "PlanSegment_Team" "PlanSegment_Team"
ON "PlanSegment"."pkPlanSegment"="PlanSegment_Team"."fkPlanSegment") INNER JOIN "Team"
ON "PlanSegment_Team"."fkTeam"="Team"."pkTeam"
GROUP BY "PlanSegment_Team"."fkTeam")
but it gives me an error of
"Only one expression can be specified in the select list when the subquery is not introduced with EXISTS."
Any help?

Don,
Thanks for your quick response.  Are you saying I just got lucky with my first expression, even though it uses SELECT?
If so, is there somewhere that will tell me exactly what SQL Expression Editor is supposed to be for? I'm trying to learn this stuff to make myself more job-marketable.
Thank you very much,
Gene
