4 87 30 88 30
5 89 40

I'm trying to make a formula that can tell me the sum of each number. Like
her, that 85 picks out that it's 10 and so on. But at 88, which isn't in the
original list, it just takes the number above. I wish it could come up as an
error, when it doesn't exist.
The formula I have used here is: =VLOOKUP(D;A:B;2)

Change your formula to this:

=VLOOKUP(D2;A:B;2;0)

and copy down. The 0 at the end of the VLOOKUP forces it to look for
exact matches, so this returns #N/A if the number is not present.

Hope this helps.

Check out...

=LOOKUP(D2,A:A,B:B)

Oops....I misread your post

Check out help on VLOOKUP(). In the below formula the last criteria is
whether to look for an exact match or not...

=VLOOKUP(D2,A:B,2,0)

To ignore this error and replace with blank

=IF(ISNA(VLOOKUP(D2,A:B,2,0)),"",VLOOKUP(D2,A:B,2,0))
