Why is the custom amount field missing?

I have selected YES to use a custom amount during the donation process, but there is no field available to type the amount. Why is this happening? You can look at the site here: followupministries.org/donate?view=cause&id=130-giving-tuesday

Thanks for your help.

Hi Esau Meza,
Thanks for contacting us and choosing our product!
I can not get access to the URL you gave, you have to change it. dear. And, our time zone is different from yours so that when you create your topic, we can not reply it at the same time. Hope you understand and sympathize with us.
