When this condition is used, the **Advanced Calculations** option must be enabled in the formula settings. * I extracted the OR part of your formula and created a separate formula to calculate only that segment. Then I connected that formula to the total cost formula, and now the correct price is being sent to the orders. * I’ve uploaded the updated calculator to the site and shared the download link with you. Please download it and test — hope it will be helpful! * Here is link -> [https://limewire.com/d/WbZcw#KHnYPfVSqG](https://limewire.com/d/WbZcw#KHnYPfVSqG) * With regards * Thread Starter [damniano](https://wordpress.org/support/users/damniano/) * (@damniano) * [6 months, 2 weeks ago](https://wordpress.org/support/topic/payment-problem-final-cost/#post-18733654) * Hi [@tomstylemixthemes](https://wordpress.org/support/users/tomstylemixthemes/) * Thank you. * I imported the file from you, but I can’t test it.

The calculator spins the wheel three times and nothing happens. The thank you page does not appear. * This only happens with Stripe. When I disable Stripe and enable ‘Cash Payment’, everything works fine. * Am I missing something? Are there any cookies or your settings left? Is that possible? Because I also noticed that when I remove the plugin and reinstall it, all settings are retained.

I assume that you are not using the calculator which i sent you. Because in my calculator all totals( formulas) are visible, in yours they are different from mine. * If you have not the calculator which i corrected the issue and sent you please let me know i will try to re-send you it. * Total is formula that is assigned as the amount of what calculator is calculating. The price which will be paid by customer. The span of the total will not solve your issue. * The error in your formula meaning that you had written some kind of negative calculation into your formula. For e.g. -100 is the summary. The calculator cannot get such price from customer. So that it is triggering error. * Hope the explanation was useful! * Kind regards * Thread Starter [damniano](https://wordpress.org/support/users/damniano/) * (@damniano) * [5 months ago](https://wordpress.org/support/topic/payment-problem-final-cost/#post-18779931) * Hi [@tomstylemixthemes](https://wordpress.org/support/users/tomstylemixthemes/) * > Because in my calculator all totals (formulas) are visible, in yours they are > different from mine. * I think I used your file, but I just added a hidden class to the formulas because the client doesn’t need to see all the calculations. * If you can send me the file again, I’ll check it once more. * What else I did: I added the “required” option to the first fields, because I think there is a problem when only the product is selected and nothing else is checked. But adding, for example, the quantity or finish seems to solve this problem. However, if you use the default settings, an error appears saying that total = 0. * [https://limewire.com/d/kCcPO#P9DbCGh6bm](https://limewire.com/d/kCcPO#P9DbCGh6bm)– Here is my current calculator, because I had to make some other changes at the customer’s request.
