Whoops! Careless of me. The line should read, and as I tested it,

elseif (eregi("[a-zA-Z]",$num)) { }

Do you see any problem with this?

I have tried with every type and mix of input that I can think of and
was successful in denying all but digit inputs, but I have little
confidence in what I am doing. With your examples I am at least
coming to some understanding of Dario Gomes article on PHPBuilder.
