what's wrong ? (regular expression - vbscript)

I probed 5.5 and 5.6 versions and the script showed 0
matches, but I think all is right and the number of
matches would be 1
what's wrong ?
tia

<%@ LANGUAGE=VBScript %>
<%
num = "279"

Set regEx = New RegExp
regEx.Pattern = "/\d{1,3}/"
regEx.IgnoreCase = True
regEx.Global = True
Set Matches = regEx.Execute(num)
response.write("matches=" & Matches.Count
& "<br>")
Set regEx = Nothing

Predictable result because the target string doesn't have slash which exists
in the pattern.

Hi Michael,
regEx.Pattern =3D "/[0-9]{1,3}/" is not valid and I don't=20
find any valid pattern. Can you help me?

According to http://msdn.microsoft.com/library/default.asp?
URL=3D/library/en-us/dnclinic/html/scripting051099.asp

Character Classes
Character classes enable customized grouping by putting=20
expressions within [] braces. A negated character class=20
may be created by placing ^ as the first character inside=20
the []. Also, a dash can be used to relate a scope of=20
characters. For example, the regular expression "[^a-zA-Z0-
9]" matches everything except alphanumeric characters. In=20
addition, some common character sets are bundled as an=20
escape plus a letter.

Symbol Function=20
[xyz] Match any one character enclosed in the character=20
set.

"[a-e]" matches "b" in "basketball". =20
[^xyz] Match any one character not enclosed in the=20
character set.

"[^a-e]" matches "s" in "basketball". =20
. Match any character except \n. =20
\w Match any word character. Equivalent to [a-zA-Z_0-9]. =20
\W Match any non-word character. Equivalent to [^a-zA-Z_0-
9]. =20

\d Match any digit. Equivalent to [0-9]. =20

\D Match any non-digit. Equivalent to [^0-9]. =20
\s Match any space character. Equivalent to [=20
\t\r\n\v\f]. =20
\S Match any non-space character. Equivalent to [^=20
\t\r\n\v\f]. =20

Repetition
Repetition allows multiple searches on the clause within=20
the regular expression. By using repetition matching, we=20
can specify the number of times an element may be repeated=20
in a regular expression.

Symbol Function=20
{x} Match exactly x occurrences of a regular expression.

"\d{5}" matches 5 digits. =20
(x,} Match x or more occurrences of a regular expression.

"\s{2,}" matches at least 2 space characters. =20
{x,y} Matches x to y number of occurrences of a regular=20
expression.

"\d{2,3}" matches at least 2 but no more than 3 digits. =20
? Match zero or one occurrences. Equivalent to {0,1}.

"a\s?b" matches "ab" or "a b". =20
* Match zero or more occurrences. Equivalent to {0,}. =20
+ Match one or more occurrences. Equivalent to {1,}. =20

Thanks Han,
I'm a perl programmer and I have a mix of ideas.

Sorry Michael,
It's incredible, My brain didn't see two slashes in your=20
message.

regEx.Pattern =3D "[0-9]{1,3}"

Many years working with perl.
