I'm using vlookup in excel to pull select data from a worksheet. The
problem
is that the value I'm seeking isn't always in the table array. So, I get
a
#n/a error. The #n/a then prevents me from summing the data that I'm
collecting using the vlookup. How do I make the #n/a go away or equal
zero
so I can sum the data?
