Har du adgang til selve databasen i Access?
Hvilken slags side taler vi om; ASP, PHP eller hvad?

Undskyld - ASP VBScript

Sådan ser siden ud!!!

burde du så ikke oprette i asp?

Det er det jeg ønsker i MX
/hans

Det er lidt svært at gennemskue hvad du laver med din querystring o.s.v. men du skal nok oprette Pris som en variabel, "fiske" enheder og enhedspris ud af Querystring og sætte Pris = Enheder * Enhedspris inden du fyrer din execute af. Jeg kan bare ikke lige se hvor det skal gøres.

Og spørgsmålet hører efter min mening også mere hjemme i ASP.

Tak

Du burde kunne lave en query i accessdatabasen som har både enheder og enhedspris som så multipliceres - dermed behøver du ikke at kode i ASP/VBScript. Sig til hvis denne fortsat er aktuel
