If the correct discount code is present, the calculated field described generates, and shows in red a negative charge of $408, so the overall transaction is zero. Yet upon "Submit" the form still goes to PayPal, but for the full $408. So how do I make the total zero and prevent it from sending to PayPal? </p> https://legacy.forums.gravityhelp.com/topic/calculated-100-negative-charge-not-being-recognized#post-98516 Mon, 03 Dec 2012 22:05:38 +0000 Chris Hajer 98516@https://legacy.forums.gravityhelp.com/ <p>I don't think you can send a negative value to PayPal. If you make the total $0, Gravity Forms will not send the transaction to PayPal. Is that what you are looking for? You could store your actual total in a hidden field if you need the number to process it offline. </p> https://legacy.forums.gravityhelp.com/topic/calculated-100-negative-charge-not-being-recognized#post-98459 Mon, 03 Dec 2012 18:27:09 +0000 strolling 98459@https://legacy.forums.gravityhelp.com/ <p>I have created a form with several fields that accumulate to a total charge, which is passed on to PayPal. This works fine. But I would like to supply some customers with a discount code to enter in a discount code field that results in zero charge, because they are being invoiced offline.</p> <p>So I have a discount code field and a product field with a calculated negative amount (adding up all the other charges and multiplying by -1), with conditional logic only to turn this on when the correct discount code appears in the discount code field. I have disabled the quantity field. The calculation formula is:<br /> ( {Would you like a standard vendor sponsorship or a Premium Vendor Sponsorship? :14} + {How many 10' x 10' spaces would you like?:15} +{Do you need electricity:8} +{Do you need to rent tents from us?:9} + {Do you need to rent tables and chairs from us?:10} ) * ( -1 ) </p> <p>When the form is filled in, this field is calculating and showing a negative value that equals the total of the fields with charges, and thus, a zero net charge. But, when clicking Submit, the form goes to PayPal and charges the full amount without the calculated discount. I would like instead for Submit to complete the process because the resulting charge should be zero.</p> <p>When I change the formula to leave out one of the values, then the calculation produces a net positive price, and this is reflected correctly on PayPal. For example if I delete the tables and chairs value from the formula, PayPal shows all the charges, a discount for everything but the tables and chairs, and a net charge for just the tables and chairs.</p> <p>So, how can I get a 100% discount to work in this situation?</p> <p>(Temporary URL: <a href="http://www.slowlivingsummit.org/soth/slow-living-expo-registration/" rel="nofollow">http://www.slowlivingsummit.org/soth/slow-living-expo-registration/</a><br /> Throwaway discount code TESTING123) </p>
