Hi guys,

Im trying to using the retrict function of textfield to allow numbers, the alphabet and the @ and . (fullstop). Essentially its for a login page im creating where users login using their email address.

For some reason I cant get it to allow fullstops (.), and the backspace key doesnt work to delete stuff in the field.

Here’s what I have:

```auto

username_txt.restrict="a-zA-Z0-9@\\.";

```

Anyone got any clues?
