Cannot post invoice or bill etc on mobile device

Not sure if it works on any other device, but on my android, the input fields for the amount are only 2 chars wide and in any case, whatever I input, it won't post.

Hello Lee,

What do you get instead?

Regards

The form looks like this. You can't see what you input and whatever you do input, it won't submit.
