My form had a textarea, a hidden product field and a total field.<br /> <pre><code>&lt;script type=&quot;text/javascript&quot;&gt; jQuery(document).ready(function(){ //NOTE: replace input_91_3 with the ID of your textarea jQuery(&quot;#input_91_3&quot;).change(function(){ gformCalculateTotalPrice(91); //NOTE: replace 91 with your form ID }); }); function gform_product_total(formId, total){ //only apply logic to form ID 91 if(formId != 91) return total; var price = 0; //NOTE: replace input_91_3 with the ID of your textarea var character_count = jQuery(&quot;#input_91_3&quot;).val().length; if(character_count &lt; 60){ price = 7; } else if(character_count &lt; 80){ price = 8.5; } else if(character_count &lt; 100){ price = 10; } else if(character_count &lt; 120){ price = 11.5; } else if(character_count &lt; 140){ price = 13; } else if(character_count &lt; 160){ price = 14.5; } //NOTE: replace ginput_base_price_91_2 with the ID of your hidden product price field (you can see it by inspecting the markup of the form) jQuery(&quot;#ginput_base_price_91_2&quot;).val(price); return price; } &lt;/script&gt;</code></pre> https://legacy.forums.gravityhelp.com/topic/calculate-cost-based-on-chars-in-text-area#post-57206 Tue, 01 May 2012 14:29:16 +0000 Rob Harrell 57206@https://legacy.forums.gravityhelp.com/ <p>Let me see if I can get any ideas on this one from the team. Sounds like it would potentially involve a customization of some kind. </p> https://legacy.forums.gravityhelp.com/topic/calculate-cost-based-on-chars-in-text-area#post-57109 Tue, 01 May 2012 05:23:32 +0000 fsluijs 57109@https://legacy.forums.gravityhelp.com/ <p>Hi guys, any news on this one? </p> https://legacy.forums.gravityhelp.com/topic/calculate-cost-based-on-chars-in-text-area#post-56209 Mon, 23 Apr 2012 12:01:14 +0000 fsluijs 56209@https://legacy.forums.gravityhelp.com/ <p>Also, a modulo function would be very useful in addition to the current calculation functions. </p> https://legacy.forums.gravityhelp.com/topic/calculate-cost-based-on-chars-in-text-area#post-56207 Mon, 23 Apr 2012 11:58:55 +0000 fsluijs 56207@https://legacy.forums.gravityhelp.com/ <p>Hi Rob, I've been trying the new functions. This looks promising!</p> <p>I do need some help with setting up the basics of the formula. How can I refer to the Paragraph Text field and get the number of characters from that field? </p> https://legacy.forums.gravityhelp.com/topic/calculate-cost-based-on-chars-in-text-area#post-56200 Mon, 23 Apr 2012 11:38:43 +0000 Rob Harrell 56200@https://legacy.forums.gravityhelp.com/ <p>You might want to try playing around with the Beta that has support for calculations to see if it could solve for this:</p> <p><a href="http://www.gravityhelp.com/gravity-forms-v1-6-4-beta-1-released/" rel="nofollow">http://www.gravityhelp.com/gravity-forms-v1-6-4-beta-1-released/</a> </p> https://legacy.forums.gravityhelp.com/topic/calculate-cost-based-on-chars-in-text-area#post-56157 Mon, 23 Apr 2012 06:01:36 +0000 fsluijs 56157@https://legacy.forums.gravityhelp.com/ <p>Hi,</p> <p>I'm using GF as a form to send advertisement text. I'd like to calculate the price based on the amount of characters in the main text area. The prices are calculated through this formula: EUR 7 for anything up to 60 characters; for each extra 20 characters we charge EUR 1,50. Max is 160 characters.</p> <p>I've been trying to get something like this going with conditional product fields, but didn't get that to work.</p> <p>Can you please help out by showing me how this can be done? I just need a small example and can copy/modify from there.</p> <p>Thanks! </p>
