i have range(a1:j1000)
columns A,C,E,G,I are phone numbers
columns B,D,F,H,J are serial numbers

i need a vlookup function that lookups up the phone number then returns the
serial number. my problem is that if the phone number being looked up is in
column C it returns #N/A
i am thinkin maybe a couple if functions, but im not sure

thanks in advance
