Appending paramaters to mod-rewrite urls

[Good2CU]

I have urls like:

www.site.com/script/paramater.html

and I try to append additional paramaters like so, within Google:

www.site.com/script/paramater.html?paramater2=x&keyword={keyword}

With my script, I want to capture the 2nd Paramater & Keyword Paramater & load them into the database.

The above doesn't work, but when I change the url to script.php?paramater1=paramater&paramater2=x&keyword={keyword}, It does work.

Is there anyway to get the www.site.com/script/paramater.html?paramater2=x&keyword={keyword} version to work with mod re-write urls?

Thanks
