JoeB Posted May 21, 2010 Posted May 21, 2010 I would love to be able to add to the JavaScript error that comes up when you do not enter anything in the checkout_payment.php page. It now says, if you do not click on a radio button that you did not select a payment method. I need help figuring out how to make one that almost does the same thing. I have discount coupon codes installed and deposit payment module that allows a customer to put down 25% or 50% or 75% towards the purchase. I need a way to have an error come up if a user uses the deposit payment plan and puts in a discount coupon code so they can not use both.A error would pop up telling them that you can only use the coupons with a full payment. I am trying to find out where the JavaScript error comes from. What php file has the code in it? If anyone has any ideas on how to code this or where I can see or learn how to do this. Thanks for everyone's help in advance. Quote
