That, of course, means that the variable you are assigning this *nothing* gets set to *nothing*, which, in PHP lingo, is null. > All I want to accomplish here is to allow the user to enter a to z, A to Z, > and /\'-_. and a space. Is there a better way to do this? 1. Do you really want to let them enter backslashes, or are you trying to "escape" the apostrophe? 2. Does that mean that "/\'-_." (without the quotes) and " " (that's three spaces) are valid entries? -- How many Vietnam vets does it take to screw in a light bulb? You don't know, man. You don't KNOW.
