PLease Help!

I have a code (written by someone else, namely BIGZELF) that will update the price on my product info page by pressing a plus or minus button. The problem that is killing me right now is that it does not take into account the specials. When a product is on special it will not display or calculate correcly. This has been a very popular script and is an extremly cool freebie from BIGZELF, so no complaints but I really need a fix or I can not use it. Thank you all so much for helping.

 

Here is the JS code I am useing:

// JavaScript Document
// calculate price based on quantity
function changeQty(change){
   var currentQty = parseInt($F('quant')) // Where quant is the id of your quantity input field. Gets value of currentQty field

   switch (change) {
       case 'add':
           currentQty += 1
           $('quant').value = currentQty
           calculate()
           break
       case 'subtract':
           if (currentQty > 0) { // only subtract if qty is greater than zero
               currentQty -= 1
               $('quant').value = currentQty
               calculate()
           }
           break
       case 'field':
           if (currentQty >= 0) {
               window.setTimeout('calculate()', 500)
           }
           break
   }
}
function calculate(){
   var startPrice = $F('base_price') // Where base_price is the id of your hidden base price field. Gets value of base_price field
   var currentQty = parseInt($F('quant')) // Where quant is the id of your quantity input field. Gets value of currentQty field

   if (currentQty > 0) { // Don't want price to display if zero if customer zeros out quantity
       var qtyPrice = startPrice * currentQty // Calculate the price.
       var qtyPrice = qtyPrice.toFixed(2) // Only allow 2 decimals. I'll let you add rounding features up or down.
   } else { // set price back to original price
       qtyPrice = startPrice
   }
   var qtyPrice = '$' + qtyPrice // Add a dollar sign
   $('priceHeading2').update(qtyPrice) // Where priceHeading2 is the id of your span for the echoed product price
   new Effect.Highlight($('priceHeading2'))
}

i've made an update.

the 3rd version should do all things correct !!

(normal price, special price (+with the old price))

 

if anybody won't at special prices, that the old price should not be shown, make the <span> (for the old price) "invisible"

or write the script better ;-)
