another rewrite question

Hi there,

my rewrite-rule is
RewriteRule ^01,([0-9]*).html$ shop/event/$1/ [L]

it´s an old rule from my php-site

RewriteRule ^01,([0-9]*).html$ index2.php?event=$1 [L]

but it does´nt work

the normal url is myapp.com/shop/event/<id>/ and I want to rewrite to it
from myapp.com/01,<id>.html

thanks for helps

guido
