您需要将您的代码与标记分开。 – IrishChieftain

你的权利，我应该但我没有时间让代码优势这只是一个quck和肮脏的构建。 –

答

这是因为你已经有了另一if内每个现有if语句...

if HP_RegularPayment < LPC_RegularPayment and **if** HP_RegularPayment < PCP_RegularPayment then

VB.NET has an operator称为If，它有两个或三个参数，以及如果所述第一是Nothing，将其返回第二个参数。

删除它，这使该行...

if HP_RegularPayment < LPC_RegularPayment and HP_RegularPayment < PCP_RegularPayment then

我也将与@IrishChieftain在他的评论表示赞同，那你真的应该分开你的代码和标记。

答

，而不是

if HP_RegularPayment < LPC_RegularPayment and if HP_RegularPayment < PCP_RegularPayment then

使用

if HP_RegularPayment < LPC_RegularPayment and HP_RegularPayment < PCP_RegularPayment then
