You can have a product with a negative value that is only conditionally shown when the Coupon Code input box gets the right value. This will update the total, and thus the total sent to Paypal. </p> https://legacy.forums.gravityhelp.com/topic/custom-field-validation-using-a-database#post-66536 Mon, 16 Jul 2012 17:00:11 +0000 webee 66536@https://legacy.forums.gravityhelp.com/ <p>is there any help on how to add coupons to the forms? and make them work with paypal please? </p> https://legacy.forums.gravityhelp.com/topic/custom-field-validation-using-a-database#post-56090 Sat, 21 Apr 2012 11:36:39 +0000 David Peralty 56090@https://legacy.forums.gravityhelp.com/ <p>You might want to hire a PHP developer to take on solving your issues as they could deal with all of them before your Sunday deadline. </p> https://legacy.forums.gravityhelp.com/topic/custom-field-validation-using-a-database#post-56075 Sat, 21 Apr 2012 01:07:38 +0000 petitshoo 56075@https://legacy.forums.gravityhelp.com/ <p>If you can, please point me in the right direction.
