Try this:

=VLOOKUP(C3,'Country List'!A:B,2,0)

If there is a chance that the country in your Datalist sheet may not
be included in the Country List sheet, then you cna change it to this
to avoid getting the #N/A error:

=IF(ISNA(VLOOKUP(C3,'Country List'!A:B,2,0)),"not
present",VLOOKUP(C3,'Country List'!A:B,2,0))

or some other message.

Hope this helps.

Can someone help me with this formula please? : )
