Previous staff have form the function below and I don't understand what it
means. He was no more longer work here. I need someone to explain what it say.

Here is the function look like
=IF(ISERR(VLOOK($A7, returnall, 32,0)*100) ,€œ €œ,VLOOKUP($A7, returnall,
32,0)*100)

Can anyone also explain why the 32 can be change to any number, what it
represent?

Thanks for anyone trying to help
