It’s because you’ve got another if within each of the existing if statement…

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

VB.NET has an operator called If that takes two or three parameters, and if the first is Nothing, it return the second parameter.

Remove it, which makes the line…

if HP_RegularPayment < LPC_RegularPayment and HP_RegularPayment < PCP_RegularPayment then

I would also agree with @IrishChieftain in his comment, that you should really separate your code and mark-up.
