I am trying to build a formula that uses a drop-down list that corresponds to different columns, it needs to capture all of the options. I was using an index match but I can only get one variable to pull and it's not pulling the correct date? A column with Current Phase has multiple drop down options that I need to match to individual columns with dates so it will pull the dates based on the phase into a Phase Completion Deadline column. Columns are not static, so I chose Index rather than VLookup.
=INDEX([Construction Completion Phase Deadline]:[Construction Completion Phase Deadline], MATCH("Construction", [Current Phase]:[Current Phase], 0)
