Hi,
First of all it's great to see our little function being put to such good use, I really like the form you've deployed!
I've noticed you use bare HTML tags in your form. Please note that the fact that doing that works at all right now is a serious bug and your form will probably break in the next week or two.
The right way to use HTML in a form (or template) is by using EmbeddedHTML, which tells the templating engine not to escape the tags.
Another thing you might want to be aware of is the $Permissions global variable that you can set to "Public" directly. This way you won't have to pass options to CloudDeploy.
And lastly (but I'm sure you've already know about this) a style suggestion.
CompoundExpression[
a,
b
]
is exactly equivalent to
a;
b
which is, in my opinion, a bit more readable.
Thanks!
Carlo
