URL Rewrite will not allow more parameters

[squiblo]

I currently have this .htaccess in my root directory

 

RewriteEngine On
RewriteRule ^([a-zA-Z0-9_-]+)$ index.php?p=$1
RewriteRule ^([a-zA-Z0-9_-]+)/$ index.php?p=$1

 

So I can type things such as "www.website.com/page", which is the equivalent of typing www.website.com/?p=page. But now I cant add more GET variables, IE this will not work - "www.website.com/page/?v=data".

 

What can I do to fix this?

 

Thanks
