Quick help on a formula

longlive289s

I know I'm missing something small and I cannot get this formula to work. Basically you throw a date into the "desired start date" and it will populate a small timeline of required milestone dates based on another sheet that's referenced. Works fine in our master sheet (right side in picture).

However when I started creating a brand new sheet, that exact same formula with the exact same columns, its giving me a "no match" error

=IFERROR(IF(INDEX({Board Meetings Range 1}, MATCH([Project Desired Start Date]@row, {Board Meetings Range 1}, 0)) = [Project Desired Start Date]@row, INDEX({Board Meetings Range 1}, MATCH([Project Desired Start Date]@row - 1, {Board Meetings Range 1}, 1))), INDEX({Board Meetings Range 1}, MATCH([Project Desired Start Date]@row - 1, {Board Meetings Range 1}, 1)))

What gives? Any help?

I'd try changing the search type in the two MATCH functions from a 1 to a 0.
