I have a schedule that has a task name column, a date column and a task type column. I am trying to build a formula (in another sheet) that will return the latest date based on when the task type is "APP" and the task name contains "GS" somewhere in the cell. Here is the formula I have come up with:
MAX(COLLECT({Schedule Date Column}, {Schedule Task Type Column}, "APP", {Schedule Task Name Column}, CONTAINS("GS", @cell)))
I am getting an "#INVALID COLUMN VALUE" error. Is there a reason why this isn't working? Can you not use CONTAINS inside of a collect?
