VLOOKUP doesn't work for me

I have a table in sheet 1 with a list of ingredients (column 1) and prices (column 2)
I want to make many sheets with recipes and the cost of each ingredient.
My question is how can I type a list of ingredients in sheets 2,3,4 etc and the price will automatically be inserted next to each ingredient?
I have tried using VLOOKUP but it doesn't seem to work for me. PLEASE HELP!
