The below should work. * ``` (function(){ if(fieldname3==’US’&&fieldname3==’MD’&&fieldname5<= 0.4) return 2; })(); ``` * Thread Starter [henrycproject](https://wordpress.org/support/users/henrycproject/) * (@henrycproject) * [8 years, 5 months ago](https://wordpress.org/support/topic/calculation-formula/#post-9805559) * Hi Damn! … no, it isn’t working with space between return and 2. * I have a dropdown selection field at fieldname3 amd fieldname4 and a number field at fieldname5. * Any other ideas? * Thanks a lot for your help in this matter. * Plugin Author [codepeople](https://wordpress.org/support/users/codepeople/) * (@codepeople) * [8 years, 5 months ago](https://wordpress.org/support/topic/calculation-formula/#post-9805576) * Hello [@henrycproject](https://wordpress.org/support/users/henrycproject/) and [@greedymind](https://wordpress.org/support/users/greedymind/), * The single quotes that are using both in the code are wrong, you are using the single quotes symbols `’’` but the correct ones supported by javascript are `''` * So, the equation would be: * ``` (function(){ if(fieldname3=='US' && fieldname3=='MD' && fieldname5 <= 0.4) return 2; })(); ``` * By the way, the equation returns a result only if the condition is satisfied. * If the issue persists, please, include in your ticket the link to the webpage where the form is inserted. * Best regards. * Thread Starter [henrycproject](https://wordpress.org/support/users/henrycproject/) * (@henrycproject) * [8 years, 5 months ago](https://wordpress.org/support/topic/calculation-formula/#post-9805617) * Thanks codeople… have copied your code but it still not working … 🙁 * Plugin Author [codepeople](https://wordpress.org/support/users/codepeople/) * (@codepeople) * [8 years, 5 months ago](https://wordpress.org/support/topic/calculation-formula/#post-9805650) * Hello [@henrycproject](https://wordpress.org/support/users/henrycproject/), * I’m sorry, but I cannot help you if you don’t include the link to the webpage where the form is inserted. * Best regards. * Thread Starter [henrycproject](https://wordpress.org/support/users/henrycproject/) * (@henrycproject) * [8 years, 5 months ago](https://wordpress.org/support/topic/calculation-formula/#post-9805651) * [https://bpeshopping.com/contact-us/](https://bpeshopping.com/contact-us/) - This reply was modified 8 years, 5 months ago by [henrycproject](https://wordpress.org/support/users/henrycproject/). * Thread Starter [henrycproject](https://wordpress.org/support/users/henrycproject/) * (@henrycproject) * [8 years, 5 months ago](https://wordpress.org/support/topic/calculation-formula/#post-9805665) * I did included it… it is hold for moderation… within 72 hours… * Moderator [Jan Dembowski](https://wordpress.org/support/users/jdembowski/) * (@jdembowski) * Forum Moderator and Brute Squad * [8 years, 5 months ago](https://wordpress.org/support/topic/calculation-formula/#post-9805737) * Spam queue.

Thanks * Plugin Author [codepeople](https://wordpress.org/support/users/codepeople/) * (@codepeople) * [8 years, 5 months ago](https://wordpress.org/support/topic/calculation-formula/#post-9805846) * Hello [@henrycproject](https://wordpress.org/support/users/henrycproject/), * Your current equation is: * ``` (function(){ if(fieldname3=='US' && fieldname3=='MD' && fieldname5<0.4) return 2.20; if(fieldname3=='US' && fieldname3=='MD' && fieldname5=0.4) return 2.64; if(fieldname5>30) return 'GREUTATE MAXIMA ADMISIBILA 30KG'; })(); ``` * Now, I will explain all errors in your equation: * First, fieldname3 cannot be at the same time equal to `'US'` and `'MD'`, so, the first and second conditional statements won’t be valid never. * Second issue, in javascript the comparison operator for equality is “==” because the symbol “=” is used for assignment, so, in the second rule the correct would be: `fieldname5==0.4` * Best regards. * Thread Starter [henrycproject](https://wordpress.org/support/users/henrycproject/) * (@henrycproject) * [8 years, 5 months ago](https://wordpress.org/support/topic/calculation-formula/#post-9805868) * got it… everything is working now! thanks a lot Viewing 11 replies - 1 through 11 (of 11 total) The topic ‘Calculation formula’ is closed to new replies. * ![](https://ps.w.org/calculated-fields-form/assets/icon-256x256.jpg?rev=1734377) * [Calculated Fields Form](https://wordpress.org/plugins/calculated-fields-form/) * [Frequently Asked Questions](https://wordpress.org/plugins/calculated-fields-form/#faq) * [Support Threads](https://wordpress.org/support/plugin/calculated-fields-form/) * [Active Topics](https://wordpress.org/support/plugin/calculated-fields-form/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/calculated-fields-form/unresolved/) * [Reviews](https://wordpress.org/support/plugin/calculated-fields-form/reviews/) * 11 replies * 4 participants * Last reply from: [henrycproject](https://wordpress.org/support/users/henrycproject/) * Last activity: [8 years, 5 months ago](https://wordpress.org/support/topic/calculation-formula/#post-9805868) * Status: resolved
