Take a look at this example: <a href="http://pastie.org/7955512" rel="nofollow">http://pastie.org/7955512</a> gomy on "User defined price with minimum amount" https://legacy.forums.gravityhelp.com/topic/user-defined-price-with-minimum-amount-1#post-273770 Fri, 24 May 2013 15:17:06 +0000 gomy 273770@https://legacy.forums.gravityhelp.com/ I'm using the authorize.net add-on and trying to set a minimum amount on a user defined price field. I'm trying to set the minimum amount to enter as $10 but for some reason its not working. Here's the code I'm using: <pre><code>// Set minimum amount on cc form to be $10 add_filter("gform_field_validation_51_7", "custom_validation", 10, 4); function custom_validation($result, $value, $form, $field){ if($result["is_valid"] && intval($value) < 10){ $result["is_valid"] = false; $result["message"] = "The minimum payment must be more than $10"; } return $result; }</code></pre> Here's a link to the form: <a href="https://www.intouchamerica.com/online-payment/" rel="nofollow">https://www.intouchamerica.com/online-payment/</a> Is there something I'm missing? Thanks
