我有一个表格，将计算的金额发送到paypal。有三个单选按钮为此，我选择第一个按钮时没有问题，它会正确计算和发送正确的数据paypal.The第二和第三是我的问题，当我选择第二和第三，先前的值或数据从第一个按钮将被发送到贝宝而不是第二或第三个值..这是一个工作表如果我选择另一个单选按钮（＃猫 - 两个工作正常，而＃cat-loto和＃cat-aerial没有提交正确的值，＃cat的值都是总是发送到贝宝代替） （这是一个问题用户回答阿兰Nisam，stackoverflow）当提交到PayPal时，Javascript表单提交数据没有变化

一个工作拨弄
更新
我发现输入呐我= “amount_1” 值= “90” 不改变的量相当于
var amount = trainthetrainerForm_calculateItemAmount();
里面的
submitTrainthetrainerForm()
功能
形式的行动
action="https://www.paypal.com/cgi-bin/webscr"
任何想法为了这？
更新
好吧，我觉得我几乎解决这个problem.The＃猫乐透和＃猫的空中值已经发送给贝宝，但如果让我选择2，3，4，5从选择#bal_number_of_members，前面的值将被选择＃bal_number_of_members.Example倍增，如果我为cat-loto选择1，它将发送正确的数字51.79，如果我更改并为#bal_number_of_members选择2， tmp_value是103.59将乘以2，它将发送给paypal的值为103.59乘以2，它应该是103.59。
