I have cloned your form and checked it on my side. I realized your text box background color and font color was white. Because of not displayed when you entered. To change it follow this steps :
1. Click the "Design" button at the top of the page. Click "Advanced Designer" button at Design screen.
2. Click your textbox field to see properties.
3. Change the font color white to black and just click "Save" button.
I hope it helps you. If you have any questions, feel free contact us.
Thanks very much - that's fixed it for me!
