Formula Vlookup help

I have created an excel invoice that uses vlookup to the orders page. The item number references to the receipt number which references to the first value over 1. I have this formula figured out. What I am having problems with is the second value because it has to find the second value greater than 1. For me this is a huge and complicated formula and I was wondering if if can be done easier. This will also get more complicated when it needs to find the third or fourth positive value.
