问题描述

我在使用以下

脚本组合购物车时遇到问题。一切都很好，总计很好，工作完美

除了你选择9.95项目＃5 BY ITSELF显示的总数是

$ 9.94！如果你添加其他任何东西，总数是正确的，无论你添加什么，9.95加

。这是这些样品中唯一能够做到这一点的价格。所有其他人都正确显示。如果您将9.95更改为

ANY其他数字，则显示正确。如果你把9.95放在任何其他

的位置（物品编号1而不是5等等它也会做同样的事情）

有什么想法吗？我完全难过了。请帮助

TIA

（这是整个html页面，你可以粘贴它并在浏览器中查看

来查看9.95项目的问题。）

I am having a problem putting together a shopping cart with the below
script. Everything displays fine, adds totals fine, and works perfect
EXCEPT if you choose the 9.95 item #5 BY ITSELF the total displayed is
$9.94 ! If you add ANYTHING else the total is correct, 9.95 plus
whatever you add. That is the only price in these samples that is
doing that. All the others display properly. If you change the 9.95 to
ANY other number it displays correct. If you put 9.95 in any other
position (Item number 1 instead of 5 etc. it does the same thing)

Any ideas ? I am completely stumped. Please Help
TIA

(This is the entire html page you can paste it and view in a browser
to see the problem with the 9.95 item.)
