Help with wildcars

Hello I would like to know if somebody could help me with wildcards function in apache and .htaccess file. I have the following code in the .htaccess that redirects a subdomain to a folder in the main domain

Options +FollowSymLinks
Options +Indexes
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} !www.domain.com$ [NC]
RewriteCond %{HTTP_HOST} ^{^([url]www.)?([/url][a-z0-9-]+).domain.com} [NC]
RewriteRule (.*) myfolder/param=%2&param2=$1 [L]

The problem is that I like to rewrite more parameters, the code just alows to rewrite (.*) as a param2=$1 and want do something like this

RewriteRule (.*),(.*) myfolder/param=%2&param2=$1&param3=$2 [L]

I tried this but doesn’t work and instead it redirects to the main domain.

I hope you can help me, please is urgent.

Thank you.
