Replace your formula with your VLOOKUP

I am using VLOOKUP and when that function doesn't find the value in the
table, it returns "#NA" as the value. I then can't sum the column
because of the #NA in some of the cells. Is there a way that I can
return a zero or a null instead of the #NA? I was thinking that perhaps
the VLOOKUP could be combined with IF... Thanks for your help in
advance.
