Authorize.net, Payment Total Field too small

Is there a way to adjust the number of characters visible in the Autorize.net Payment Total Field?

Here is our form and my clients complain that they can not see the the entire amount the type into that field

Inject the following custom CSS codes to your form: 

input#input_14_donation {

    width: 100%;

}

Here's how to inject: http://www.jotform.com/help/117-How-to-Inject-Custom-CSS-Codes. Please add it to the bottom.

You can change the value if you think the width is too wide.

Thank you, works perfect!
