need help with lookup function

[wii]

WHEN USING VLOOKUP.....


I am looking up an item in 2 different tables, however sometimes th
item is not in both tables.

When the one table does not have the item, excel returns a (n/a
entry.

How do I program it to use a default value of 0 when no record i
found???


=VLOOKUP(A2,WAUKREF!A2:S1000,18,0)
+VLOOKUP(A2,WWREF!$A$2:$S$1000,18,0)

I THOUGHT MAYBE "0" IN THE ARGUMENT, BUT IT IS NOT WORKING.

IT IS BEING USED TO AUTO CALCULATE THE COMBINATION OF THE TWO FEILDS

ANY HELP WOULD BE GREATLY APPRECIATE

Try this:

=if(isna(VLOOKUP(A2,WAUKREF!A2:S1000,18,0)),0,VLOOKUP(A2,WAUKREF!A2:S1000,18,0))

+if(isna(VLOOKUP(A2,WWREF!$A$2:$S$1000,18,0)),0,VLOOKUP(A2,WWREF!$A$2:$S$1000,18,0))

Should give you what you want - the lower case will convert to upper
case once you type it in.

Hope this helps.
