Supposing that you have two values in your field: 0 (with the title "no") and 1 (with the title "yes"), and supposing that the column name of your custom field is "custom_field" and that your custom field is a custom field of the table "item", you could write this formula: Code: {price}+6.25*{custom_field} If the value selected is "no", then the formula will be {price}+6.25*0 and thus the calculated price will be equal to the base price of the product. If the value selected is "yes", then the formula will be {price}+6.25*1 and thus the calculated price will be equal to the base price of the product plus 6.25.

But i still have trouble understanding this kind of formulas. Now the first field is working, but the second field in the same product is not. I made a extra formula. But it's not counting. It's for a soccer shirt. First field is for a name on the back, second field is for the number on te back of the shirt - [ ![2025-01-1522_39_08-Plugins_Hikashop-PriceCalculations-Voetbalstars-Administration.png](/forum/attachment/60144) ](/forum/attachment/60144 "...nistration.png") [ ](/forum/attachment/60144?download=1 "...nistration.png") Please [Log in](/login?return=aHR0cHM6Ly93d3cuaGlrYXNob3AuY29tL2ZvcnVtLzI2LXByb2R1Y3QtY2F0ZWdvcnktZGlzcGxheS85MDkwMzQtcHJpY2UtY2FsY3VsYXRpb25zLXBsdWdpbj90bXBsPW1hcmtkb3du) or [Create an account](/component/users/registration?Itemid=101) to join the conversation. - **[nicolas](/forum/user/63-nicolas "View nicolas's Profile")** - [![nicolas's Avatar](https://www.hikashop.com/media/kunena/avatars/resized/size144/users/avatar63.png?1793428657)](/forum/user/63-nicolas "View nicolas's Profile") - [ Offline](/forum/user/63-nicolas) Less More - Posts: 86359 - Thank you received: 14293 - - 1 year 9 months ago [\#365271](#365271) by [nicolas](/forum/user/63-nicolas "View nicolas's Profile") Replied by *[nicolas](/forum/user/63-nicolas "View nicolas's Profile")* on topic *[Price Calculations plugin](/forum/26-product-category-display/909034-price-calculations-plugin#365271 "-- HikaShop version -- : 5.1.2 -- Joomla version -- : 4.4.10 -- PHP version -- : 8.1 -- Browser(s) name and version -- : Chrome i can't seem to figure it out.

So you need to merge both formulas together: Code: {price}+6.25*{custom_field}+6.25*{custom_field2} Please [Log in](/login?return=aHR0cHM6Ly93d3cuaGlrYXNob3AuY29tL2ZvcnVtLzI2LXByb2R1Y3QtY2F0ZWdvcnktZGlzcGxheS85MDkwMzQtcHJpY2UtY2FsY3VsYXRpb25zLXBsdWdpbj90bXBsPW1hcmtkb3du) or [Create an account](/component/users/registration?Itemid=101) to join the conversation.
