Problem med JavaScript. HJÄLP!!!
Hej!
Jag gör hemsidan till www.teknik-experten.se men sen fick jag ett problem i kundvagnen. Det går inte att räkna summan av produkterna med hjälp av funktionen "calculate(pris)". Gå in på teknik-experten.se och tryck på köp i en valfri produkt. den kommer att läggas till i kundvagnen men den räknar inte summan av priset. Se på de här koden nedan: (ni hittar problemet på www.teknik-experten.se)
