        Form5.Adodc1.Refresh
        Form5.DataGrid1.Refresh
        Form5.Show
    End If
End If
End Sub

my logic here is if i deduct 2 to 10 (where 10 is the current stock) then 2 will be add to database fields(Previous Stocks/Last Week Stocks)

note for Mr. AndreRet : I rename my Database Field Last Week Stocks to Previous Stocks

Please help...

@Master, sorry being weekend and all, I will not be spending a lot on this. Maybe tomorrow if I have a huge hangover.;)

Your logic is not as good. Zip and load your app again with the database, let me change some code. I will not do the entire project though. only up to with what we are busy with.:)
