How to remove Country from Authorize.net

I asked this question last week and got a similar response as someone else did below...

"There's no option to hide the country dropdown field, but we can visually hide it using CSS. If that's the form you're working on, inject these CSS codes to your form builder:"

#input_38_country, #sublabel_38_country {

    display: none;

}

THE ISSUE IS THAT WHEN I TEST THE FORM, IT GIVES AN ERROR SAYING THAT YOU MUST FILL OUT THE FORM COMPLETELY. IT WILL STILL WILL NOT ACCEPT MY CREDIT CARD BECAUSE IT IS HIDDEN, BUT NOT COMPLETED. 

CAN I SOMEHOW SET IT TO DEFAULT TO THE UNITED STATES AND THEN HIDE IT? I HAVE LOOKED INTO CUSTOM JAVA SCRIPT, BUT YOU DON'T SEEM TO ALLOW THAT. 

I NEED TO REMOVE ALL OF THE OFAC COUNTRIES.

Unfortunately, it's not possible at the moment to remove fields from the Authorize.net payment field, the CSS option will not work due to the error you've already experienced. 

I can see you have already asked this before and your thread was escalated to our back-end team here: https://www.jotform.com/answers/1989293- 

Please note that you will be updated on that thread as soon as we get anything from our second level. 

Thanks.
