Replacing parameter in url using htaccess

Im trying to replace my url

my-url.com/profile/?name=PARAMETER

to

my-url.com/profile/PARAMETER or my-url.com/profile/PARAMETER/

I tried this:

RewriteRule ^profile/([0-9]+)/$ profile/?name=$1

but it didn't work. Can you give me some example how to do this?

PS: Sorry for bad english ;)
