Once the iframe has loaded, the user can still choose another card type. We have a cancel button so that the user can have the feeling of ending the donation process with clear feedback that nothing has been charged to their card. I think @MBeat33 and donor services would get concerned emails if this wasn't available. This might need A/B testing and I'd want to hear from advancement leads if this is worth prioritizing.

Thank you for the prompt response @DStrine!

I see your point about giving the user a way to cancel the donation at this point in the process and you're right. I believe I wasn't specific enough, sorry about that. What I meant was to remove the CANCEL button from the context of the card.

I'm attaching a mockup that doesn't require any logic change and will make it clear for the user what will happen if they choose to click there, while at the same time echoing the same message in the next page. After all, it's not an error if they cancel, as the current page mentions. This would reduce errors in the user's end.

Let me know your thoughts, thanks!

@spatton @jrobell @Ppena Do we just want to do this across the board or does anyone want to A/B this? The latter will take more work.

How much more work will it take to set up for an a/b test vs. directly implementing, @DStrine?

The hosted payment form editor didn't let us remove the button when we were first setting it up, so we had hidden it by setting it to white on white. It was still clickable though, so people were hitting it by mistake.

@spatton I didn't know that we already got bad feedback on this. If we try to make the button blend into the background, I think we'll still have this problem. We could try this again but DS and @MBeat33 would need to be very attentive during the test. Do you still want to proceed?

That 'successfully canceled' error message mockup looks like it should be do-able with a bit of development.

Thanks @Ejegg and @DStrine, I agree that if we can't completely remove the cancel link from the form, we shouldn't try to hide it thru style changes.

Nice to know re: @scervantes's 'successfully canceled' error message mockup + Cancel link color change, Ejegg: I'd be happy with that solution.

Note to reviewers: I left the border around the cancel button visible so as not to lead mobile donors to use the area as a resting zone for their fingers (we heard this was happening with the hidden button before).
