Trying to sum a column that was built using VLOOKUP. Several of the values
returned in the column are #NA. The column will not sum. How can we write
the VLOOKUP formula to return error values = to 0 rather than #NA?

Embed your vlookup inside an if. Instead of =vlookup(...), use
=if(isna(vlookup(...)),0,vlookup(...))

You could change the Sum() formula:

=SUMIF(A1:A20,"<#N/A")

Another way - adjust your VLOOKUP formulae to the following:

=IF(ISNA(VLOOKUP formula),0,VLOOKUP formula)

and copy this down.

Hope this helps.

Pete

General soln is

=IF(ISNA(Your_Formula),0,Your_Formula)
