Regex validation not working correctly

I have added regex validation to a few fields and it doesn’t appear that it is correctly evaluating them:

For a “Name” field I have ([a-zA-Z0-9\!\_\-)]).
It is supposed to allow only upper and lower case letters, 0 to 9, !, _ and – characters. When running it through a Regex validation tool it correctly highlights the correct dataset. When signing up on the form though it allows anything to go through.

Also for another field, -?[0-9]{1,4},-?[0-9]{1,4}, does not work.

It is supposed to be any positive or negative number between 0 and 9999 in the format 0000,0000.
