Can't confirm/submit my donation

[charityneverfaileth25]

I'm trying to submit a donation on the church's website, but nothing I try gets me past the point where it asks me to "reenter" the amount I've put in (due to the amount being larger than normal). It gets stuck there, even though I enter in the identical amount, and won't allow me to confirm the donation and continue to submission. I've tried 4 different web browsers, and get much the same, with the mobile safari browser not even allowing me to see the donation form.

Is this a known issue?

Follow-up: Confirm Button Disabled Due to Floating-Point Precision Mismatch

I’m following up on my original post regarding the donation confirmation pop-up, where the "Confirm" button remains disabled even when the correct amount is entered. With the help of some AI, I have drafted the following bug report:

Summary of Issue
When entering donation amounts that visually sum to $75.73, the confirmation field fails to validate—even when 75.73 is typed in exactly. The checkmark indicator remains grey, and the "Confirm" button stays disabled.

After inspecting the DOM and running diagnostics in the browser console, I discovered that the issue stems from a floating-point precision mismatch between the calculated Donation Total and the value expected by the confirmation logic.


Technical Findings
Here’s what I observed:

I entered the following donation amounts:

Tithing: 50.73

Fast Offerings: 20.00

Humanitarian Aid: 2.50

General Offerings: 2.50

These values visually sum to $75.73, which is displayed correctly in the UI. However, the underlying amount attribute on the confirmation pop-up is set to 75.72999999999999.

This discrepancy causes a strict comparison to fail when entering 75.73 into the confirmation field.

Console Output:

Input Values: [50.73, 20, 2.5, 2.5]
Raw Sum: 75.72999999999999
Rounded Sum: 75.73
Reported Total (from DOM): 75.72999999999999
Totals do NOT match. Possible floating-point precision issue.


Suggested Fix
To resolve this, I recommend rounding the calculated Donation Total to two decimal places before passing it to the confirmation pop-up. This would eliminate floating-point precision errors and ensure consistent validation.

Example Fix:

const roundedTotal = (Math.round(total * 100) / 100).toFixed(2);

This would ensure the amount attribute reflects the same value users are expected to enter, allowing the checkmark to activate and the button to enable as intended.

Thanks again to the developers and forum moderators for reviewing this. I’m happy to provide further details or test additional scenarios if needed. I hope this helps improve the experience for others encountering the same issue.

Thanks again to the developers and forum moderators for reviewing this.

Actually, the developers are not here. This is a user-to-user forum where we help each other based our experiences.

I would suggest you report this finding using the Feedback link at the very bottom of the donations page. That will get the issue before the developers. You are welcome to provide a link to your post to assist them with the details.

I am curious about one thing, though. When I make online donations at the official Church donations site, there is no provision for me to enter a total before I click on the Submit button. The form self-totals. There is no place for me to enter a total amount for the site to compare with its own total.

In any event, the Feedback link will get the information you are providing to the developers.
