Selecting boxes on an iPad

Hi guys - quick issue, I am outputting courses in HTML 5 for use on iPad, I have a slide with 2 text boxes. Once the 2nd text box entry has been added, I can't see to Submit the slide.

You can see on the image below, there is no way of scrolling down the slide which stops the course in it's tracks! The return button doesn't work, the Next button is greyed out...

Anyone else had issues with this? Any ideas?
