Hi,
If the matching data is only present in one or the other the 2 sheets, (ie,
not both) and if you are using FALSE (or 0) as your 4th argument in your
VLOOKUP's, you could try something like this:
IF(ISNA(VLOOKUP(1st Sheet Lookup Details),VLOOKUP(2nd Sheet Lookup
Details),VLOOKUP(1st Sheet Lookup details))
When using FALSE (or 0) as your 4th argument, VLOOKUP returns a #N/A when
its lookup value is not found.

If the value is definitly on one of the two sheets and only on one of the two
sheets - this formula has no provision for a value with no match and will
return #N/A in that case...
=VLOOKUP(A2,IF(LOOKUP(A2,DataSheet!$A$2:$A$30)=A2,DataSheet!$A$2:$B$30,DataSheet2!$A$2:$B$30),2,0)
where A2 contains the value to lookup...
if lookup finds a matching value in the first column of data in the first
data sheet:
LOOKUP(A2,DataSheet!$A$2:$A$26)=A2
then the table for lookup would be that sheet:
DataSheet!$A$2:$B$26
if not, it will be the second sheet:
DataSheet2!$A$2:$B$30
In this example, returning data from the second column when there is an
exact match...
substitute as necessary.

LOOKUP requires the lookup_vector be sorted in ascending order.
Try this:
=VLOOKUP(A1,IF(COUNTIF(Sheet2!A1:A5,A1),Sheet2!A1:B5,Sheet3!A1:B5),2,0)
