When was the INDEX function released?
Was it this one?
I can find no reference to it in the release notes (searching the whole page), the last version of the Formula Examples does not mention it nor does the blog entry for this release.
It is mentioned here:
http://help.smartsheet.com/articles/775363-using-formulas
but that only tells me it exists.
Which is nice. MATCH is more powerful when paired with INDEX.
