Hej jag har en liten shop där man kan lägga in hur mycket man har av varje produkt på lager tex man har 5 hemma. Men jag vill när kunden klicka på köp så ska det ändras i databasen till 4 osv. Här är sidan men jag har försökt att klura ut hur man gör men fattar tyvärr inte att och ber verkligen om er hjälp.
