Each with it's own price. You can then use conditional logic to hide/show the appropriate field based on the drop down values. Only the visible product field will be sent to paypal and recorded in the entry, so it would essentially act like the price was changed. </p> https://legacy.forums.gravityhelp.com/topic/dynamically-adjusting-price-field-on-product#post-19838 Thu, 03 Mar 2011 15:40:05 +0000 Dave Landon 19838@https://legacy.forums.gravityhelp.com/ <p>any idea on how to accomplish this?

Basically I am using some jQuery calls to update the price.

This is for security reasons so users can't manipulate the price and purchase at a cheaper price by spoofing it.</p> <p>How are you dynamically changing the price currently? If you describe what you are doing, what hooks you are using or how you are doing it we may have a work around. </p> https://legacy.forums.gravityhelp.com/topic/dynamically-adjusting-price-field-on-product#post-19761 Wed, 02 Mar 2011 17:21:43 +0000 Dave Landon 19761@https://legacy.forums.gravityhelp.com/ <p>Hi,</p> <p>I am currently developing a paypal / gravity forms solution. Right now I'm experiencing a strange validation error. Basically, when I change the price on a product and the form validates it tells me that the price fields needs a correct value. However this only occurs when the price is DIFFERENT than the value upon the initial page load.</p> <p>That being said, I believe that the form is validating against the original price.</p> <p>Confirming my belief, when the form reloads and lets me know that the price needs a correct value, I can submit the form and it works as intended.</p> <p>Any insight on how I can overcome this problem??</p> <p>Any and all help is appreciated!</p> <p><a href="http://development.cftacs.org/registration-forms/?fid=31&amp;firstName=Chris&amp;lastName=Carvache&amp;courseTitle=Robbery%20Preparedness&amp;courseNumber=Spring11Web115Web21010%2F20%2F2011&amp;email=chris@northeastwebdesign.com&amp;coursePrice=255.0000&amp;delivery=Webinar&amp;deliveryType=Live+Webinar&amp;courseDate=October+20th%2C+2011&amp;courseTime=11:00%20AM" rel="nofollow">http://development.cftacs.org/registration-forms/?fid=31&amp;firstName=Chris&amp;lastName=Carvache&amp;courseTitle=Robbery%20Preparedness&amp;courseNumber=Spring11Web115Web21010%2F20%2F2011&amp;email=chris@northeastwebdesign.com&amp;coursePrice=255.0000&amp;delivery=Webinar&amp;deliveryType=Live+Webinar&amp;courseDate=October+20th%2C+2011&amp;courseTime=11:00%20AM</a></p> <p>Sorry for the long link! </p>
