specify what a field will accept

I want to specify that a field only excepts numbers but it is not a "required field"

How do I do this?

RE: specify what a field will accept

You can do this with javascript to validate within the browser or you can do this with whatever scripting language your server supports (ASP/PHP/Perl/etc) to validate during form processing on the server.

There are specific forums here for javascript and server side languages. You'll get a more specific answer there once you decide which language you will be using to script this.

The key search phrase that might help you on your path at Google is 'form validation'

RE: specify what a field will accept

Just to add to this, personally I'm of the belief that you should do your validation on both the server and the client side. If you do the validation only with Javascript then you will not be able to stop them submitting something other than numbers if they have JS disabled.
