Once I get the script sorted I can embed it with this -- thanks! Unfortunately I'm having a heck of a time actually getting my script to change the value. I'm also having trouble comparing the values as they are strings not integers. Do I have to strip out all the other characters "." and "," - I've just started by striping the "$" but didn't go further as I wasn't sure if this was the right way to go.</p> <p>My main issue though is I can't seem to change the value of total. In the code below I just have it trying to replace it with "123". Ultimately I would just add the deductible back into the total if condition below is true.</p> <pre><code>$(&quot;#gform_next_button_2_4&quot;).click(function(){ var deductible = $(&quot;#input_2_12&quot;).val().replace(&#39;$&#39;, &#39;&#39;); var total = $(&quot;#ginput_base_price_2_6&quot;).val().replace(&#39;$&#39;, &#39;&#39;); if ((deductible) &gt;= (total)) { $(&quot;#ginput_base_price_2_6&quot;).val(&#39;123&#39;); $(&quot;#input_2_6&quot;).val(&#39;123&#39;); } });</code></pre> <p>I know this is above and beyond, but if you have a few moments to look at this awesome. If not, no worries! </p> https://legacy.forums.gravityhelp.com/topic/prevent-negative-number-in-calculation#post-140830 Sun, 03 Feb 2013 23:37:01 +0000 Chris Hajer 140830@https://legacy.forums.gravityhelp.com/ <p>To add jQuery to your Gravity Form, you can enter it into an HTML field in the form, or you can add it to the head section of the page where the form is embedded. If you want to add it to the head section of the page, you can use the gform_enqueue_scripts filter:</p> <p><a href="http://www.gravityhelp.com/documentation/page/Gform_enqueue_scripts" rel="nofollow">http://www.gravityhelp.com/documentation/page/Gform_enqueue_scripts</a></p> <p>The script you write will be pretty simple. It will watch for the inputs and then perform your calculation and populate another field with the result. </p>
