I should have said, this is JavaScript. Based on the above, and I was trying something similar, I
have this:
var ff = RegExp("[0-9]*").test(numtext.value)
alert(ff)
But it's not right, I get true every time. We need to exclude alpha characters and special
characters (like the *). My guess is my syntax is not quite right?
