That's ok,I worked it out now.Thanks's for you'r help and one last question I hope if you can answer this one for me?How do I bring down the country resources average quality down to 100,say from 200 for example,how long will it take for those average quality products down to 100 and how do I do it.My way of thinking is buying for the country needs then set the average quality at 100 on all of them as I go down the list,will the average quality will eventually come down to 100?or not?Thank's.Other wise do I have to drain all the resources and start again?
