I am attempting to do a lookup of a a Date (on the Deliverable Tracker, shown in screenshot #1). The lookup will use the Effective Start and End dates to find the appropriate range, then the end result will be the text value column at the far right. My formula shows a blank result, here is the formula:
=IFERROR(INDEX(COLLECT({Lookup Table_Text_Value}, {Lookup Table_StartDate}, <=[Date Submitted]@row , {Lookup Table_EndDate} >= [Date Submitted]@row , {Lookup Table_Primary}, "Option Period"), 1), "")
