>>> [!note] Migrated issue <!-- Drupal.org comment --> <!-- Migrated from issue #2272599. --> Reported by: [Anthony Goode](https://www.drupal.org/user/1848844) >>> <h3>Description</h3> <p>Webform Calculation Components provides AJAX functionality to perform basic arithmetic operations on webform components. With this module the user can have calculated fields, e.g. the total amount, calculated percentage etc.<br> This module provides two new webform component types, Caluculation number and Calculation hidden.</p> <p>Typical use cases are:</p> <ul> <li>Inserting simple formulas in the webform.</li> <li>Calculations in a spreadsheet fashion (I recommend that you create new Calculation number fields). E.g. the total amount is the sum of the column of amounts above.</li> <li>Quotation forms to estimate prices without using the functionality of an ecommerce module. E.g. If the user checks a select option it adds the price of an element to the total price. (I recommend that you create new Calculation hidden fields).</li> </ul> <p>The configuration of the components is like any other webform component. This project allows non-technical users to configure calculations using an easy user interface.<br> It has been tested to support webform-4.x .</p> <h3>Sandbox</h3> <p><a href="https://drupal.org/sandbox/anthony_goode/2272403">https://drupal.org/sandbox/anthony_goode/2272403</a></p> <p>There are screenshots with two examples and the corresponding settings.</p> <h3>Git</h3> <pre><pre>git clone --branch 7.x-1.x http://git.drupal.org/sandbox/anthony_goode/2272403.git webform_calculation_components<br>cd webform_calculation_components</pre></pre><p>This project has been developed because I have often read requests to insert some kind of calculated fields (including my business partner).
