You are declaring the stocks variable and using that variable in the expression that initialises it:

Dim stocks = New Stocks With { .QTY_STOCK = (stocks.QTY_STOCK - detail.Qty),

How can stocks.QTY_STOCK possibly have a value there when that's the property you're setting with that code? You haven't bothered to explain what you're actually trying to achieve with that code so we can't tell you what it should be like, but it definitely shouldn't be like that.
