sql max help

I have a table with the following
TISYSTEM TILABEL TILOCATE TISEQ TITAPEDATE
RG FRIDAY VAULT 1 20,130,614
RG FRIDAY VAULT 2 20,130,524
RG FRIDAY VAULT 3 20,130,531
RG FRIDAY VAULT 4 20,130,607
RG MONDAY VAULT 1 20,130,614
RG MONDAY VAULT 2 20,130,524
RG MONDAY VAULT 3 20,130,531
RG MONDAY VAULT 4 20,130,607

I am trying to get the value of TISEQ for the record with the highest date for a specific system, label, location

So I have the following query and it works fairly well, except I seem to get two records back

SELECT TISEQ FROM tapeinv00 WHERE titapedate = (select
max(titapedate) from tapeinv00 where tisystem = 'RG' and TIlabel =
'FRIDAY' and tilocate = 'VAULT' )

What I would hope to get for this query is 1
I get two records with 1 returned and I'm not sure why.
Ideas?
Better way to do this query?

Thanks

Mike
