mod-rewrite

Hello everyone.

I'm trying to redirect an easy to remember url to a php file but I'm having some trouble with the regex.

Here's what I have at the moment:

RewriteRule ^tcb/([a-zA-Z0-9]{1,})/([a-zA-Z0-9]{1,})/([a-zA-Z0-9]{1,}) /tcb/lerbd.php?autocarro=$1&tipo=$2&dsd=$3

It is working but only if I supply all 3 arguments. I want the last two arguments to be optional so it either works with only the first or all three. I'm hoping you can help me with this.

Thank you very much.
