Hi,

In my ms sql database i have 2 numeric fields.
I declared 2 variables and a calculation :

Brutto = (Producten.Fields.Item("BruttoPrijs"

.Value)
Netto = (Producten.Fields.Item("NettoPrijs"

.Value)
Winst = Brutto - Netto

I get a code error.
This is my code in asp vbscript:

<%
Brutto = (Producten.Fields.Item("BruttoPrijs"

.Value)
Netto = (Producten.Fields.Item("NettoPrijs"

.Value)
Winst = Brutto - Netto
%>

Help is very welcome.

Tx,
Peter

I don't know the error you get, but try converting the values to Double first.

Brutto = CDbl(Producten.Fields.Item("BruttoPrijs").Value)
Netto = CDbl(Producten.Fields.Item("NettoPrijs").Value)
Winst = Brutto - Netto
