Hey JoeyJoe.
Welcome to the Community!
I'm sorry to hear of the difficulties that you have been encountering when trying to complete an application to create an app through the website. We would advise that you try this on a different device and also delete your temporary internet files as this may help.
If you still experience difficulties at this point, we would advise that you submit a request to our technical teams through the following link https://developer.paypal.com/support/
I hope this helps.
David.
