Hi everyone
I have a bit of dillema here.
How can I control that a client cannot enter two different prices for the same Item.
Ex.: If the Item is Bicycle and it's code is 1001, and the price is 1234.9$, how can I stop someone from entering that same Item but with different price.
Thank you so much
