Hi I am using Magento 1.7.0.2 and the price is set to 0 automatically if I have custom options in the product. But the price is set to 0.00 while page is loading first it’s showing and automatically go to 0.00 I was googleing to find a solution but there is now solution. I tried to change product.js on line 572 i’ve changed this.plusDispositionTax = config.plusDispositionTax; to this.plusDispositionTax = 0; After i do this the price is showing but when I chose some option the price from the option menu is not added to the main price. to see what I mean please follow this link http://weddingbelles.com.au/index1.php/proba-za-cena.html
This will ensure that if the item is set to a number, it will get through for you. If its not set, at least it doesn’t crash the parseFloat which results in a NaN and hence $0.00
