The formula itself doesn't return #N/A as written, you might have a N/A
error in any of the ranges
For instance if your results in any of the columns are derived from either
lookups or match then that formula might result in N/A which will make the
sumproduct formula returning it as well

Use F5, click special and look for formula errors

Hi. Does anyone see anything wrong with this formula? It returns an
#N/A and I have no idea why?! Thanks!

=SUMPRODUCT(--(MPD!$B$2:$B$18000=I1),MPD!CE2:CE18000,MPD!$CD$2:$ CD
$18000)
