how to fit a price variable box on in the form

Hi, as you can see by the screenshot- when I added a "my best gift" option to our donation page, the area where you would type in an amount is stretched off the screen (see red arrow).

How can I keep that box (where you add your donation amount) smaller?

Thanks!!

Inject the following custom CSS code as explained on this guide: http://www.jotform.com/help/117-How-to-Inject-Custom-CSS-Codes

#input_9_1011_custom_price{

    width: 25px !important;

}

It should fix the problem:
