Correction:
To be "100%", change the occurrences of "match(0)" to
"match.item(0)" . Also note that the IsNumeric test will
validate scientific notation; e.g., 10+ or 10- will return "true"
from IsNumeric---in case that might be a problem.

Here you go, Craig.
Just copy the following as some xxx.asp file and execute. This
not only shows you how to do it, but the document will allow you
to test various combinations of characters to see if they contain
a number. The algorithm only tests for numbers at the BEGINNING
of the string. characters allowed are 0-9, + and -.
Hope this helps....
