    Script to calculate the discount amount..


      Hi, I need a script to calculate the following;



      Package Weekly Amount = £100

      Package Discount Percentage field = 10%

      Package Discount Weekly Amount = -£10

      Subtotal = £90


      The script I have does not work and my knowledge of javascript is limited.


      My script:


      var a = this.getField("Weekly Amount");
      var b = this.getField("Package Discount");
      event.value = a.value - (a.value * (b.value/100));


      Any help with this would be appreciated.
