How can I increase width of PayPal payment field?

I have calculated totals to pass to a PayPal gateway using the Custom Amount Payments.

To widen the Total Amount Due field, I have injected the following CSS

#input_70_donation {
    width : 122px;
  font-size : 12px;
}

When viewing in design mode, it looks correct.  Once I save the changes, it reverts back to the original size.

What am I missing?

Thanks,

There is an error in your CSS which is why the PayPal field is not working properly. Please remove that CSS code in the Form Designer:
