The Total value in the Payment Integration is too narrow (total is being cut off)

As you see in the screenshot, the total is cut off.

Is there a way of widening this field? Payments are via Paypal.

Thx!

Yes, the width of that field can be changed using Custom CSS.

(How to Inject Custom CSS Codes)

I have added the following CSS to your form.

#input_21_donation {
  width: 100%;
}

Feel free to change the value of the field's width. You can also use pixels instead.

#input_21_donation {
  width: 100px;
}

This doesn't seem to have worked on another form...

For that form, it should be #input_13_donation. Here's the code:

#input_13_donation {
width: 30%;
}

Here's the result:

Hope that helps. Thank you.
