If you are getting a number from a user via a form you can use
javascript to verify that the user inputed a number...
search google - validating forms that should give you some info.
You could also verify that the data is a number by is_numeric or
is_int...
I think that when the data is POSTed that it will be a string so you can
use is_numberic to verify if it is...

I have a repeating function to add. The user enters the number of how many
numbers they want to add, then it repeats a form field. What I want to do is
detect to make sure that the value they enter is a number. If not, don't do
the do while loop and if it is, then go ahead and do it. How can I do this?
Thanks,
