Title: Error: Invalid payment amount Last modified: April 12, 2026 --- # Error: Invalid payment amount * Resolved [elmonty](https://wordpress.org/support/users/elmonty/) * (@elmonty) * [1 week, 2 days ago](https://wordpress.org/support/topic/error-invalid-payment-amount-8/) * I updated to Forminator 1.52.2. A user submitted their entry with total amount of $518 and got “Error: Invalid payment amount.” I have screenshots of their entry. * Last year when I updated Forminator, it also caused errors. * I temporarily made the Dues field optional so that I could test it without submitting dues myself. I entered $1 in “Additional donation” and it submitted successfully. * Here is the export of my form: [https://pastebin.com/k7dHtcj6](https://pastebin.com/k7dHtcj6) Viewing 11 replies - 1 through 11 (of 11 total) * Thread Starter [elmonty](https://wordpress.org/support/users/elmonty/) * (@elmonty) * [1 week, 2 days ago](https://wordpress.org/support/topic/error-invalid-payment-amount-8/#post-18878468) * I recreated the form from scratch and rounded the calculation of the total amount to an integer. Still having the same error. Users are unable to submit a payment.

The form submissions, including payment amounts, are going through as expected without triggering the _“Invalid payment amount”_ error. * To help us investigate this further on your setup, could you please provide a bit more detail on how the issue occurs? - The **exact steps** to reproduce the issue (e.g., which fields are filled and with what values) - Whether the issue happens consistently or only in specific cases - A **link to the form on your live/test site**, if possible * This will allow us to better understand what might be triggering the error in your environment and guide you more accurately. * Looking forward to your update — we’ll be happy to continue investigating this with you. * Best regards, Mina Emad * Thread Starter [elmonty](https://wordpress.org/support/users/elmonty/) * (@elmonty) * [1 week, 1 day ago](https://wordpress.org/support/topic/error-invalid-payment-amount-8/#post-18878933) * Do you have a private email I can send the info to? * Thread Starter [elmonty](https://wordpress.org/support/users/elmonty/) * (@elmonty) * [1 week ago](https://wordpress.org/support/topic/error-invalid-payment-amount-8/#post-18879997) * I can send screenshots of the form filled out if you give me a private message address.

You’ll have to change two places to get the solution in the form. * 1. Need to change the checkbox-2 field’s calculation value to `0.35` from `0.035` Screenshot ref: [https://monosnap.ai/file/e1Z4G5f5EnFxpEuK6xe80zDlyjPRnI](https://monosnap.ai/file/e1Z4G5f5EnFxpEuK6xe80zDlyjPRnI) * 2. Then change the formula in the calculation field and use `({checkbox-2}/10)` instead of ` {checkbox-2} round(({radio-1}+{checkbox-1}+{number-1})*(({checkbox- 2}/10)+1)) ` Screenshot ref: [https://monosnap.ai/file/VSV3kL6Kd7220ahhOgGD4x1mD9oxXa](https://monosnap.ai/file/VSV3kL6Kd7220ahhOgGD4x1mD9oxXa). * Please give it a try and share the outcome. * – Kind Regards, Imran Khan - This reply was modified 5 days ago by [Imran - WPMU DEV Support](https://wordpress.org/support/users/wpmudev-support9/). * Thread Starter [elmonty](https://wordpress.org/support/users/elmonty/) * (@elmonty) * [4 days, 19 hours ago](https://wordpress.org/support/topic/error-invalid-payment-amount-8/#post-18883679) * Thank you for coming up with a workaround quickly.
