Why doesn't the progress of a match/ challenge match the campaign or landing page total?

Main reasons a match/ challenge will have different donor or dollar counts:

1. Matches and challenges only count gifts made while they are live- a gift made prior to the match/challenge going live are not counted.

2. Gifts only count into matches and challenges at gift time. If a gift is edited later to add an affiliation or designation it will not retroactively count into a directed match/challenge

3. Matches/challenges do not count themselves or other matches/challenges into their count. This is especially noticeable for a landing page- the match/challenge itself and other matches and challenges might count into a landing page, but won't count into the match/challenge, even if they are directed to the same thing.

These same reasons can also factor into differences you may see between a leaderboard or landing page and a math or challenge that are both directed to the same designation. The leaderboard and landing page are always going to show all gifts to that designation (including matches and challenges) which the match or challenges will only show gifts (not matches and challenges) that have been made to that designation while the match or challenge has been live.
