Passing Muliple Parameters with remote_function

Rails
1

<select name=“media” id=“media” onchange="<%= remote_function(
:url => { :action => :show_performer_categories,
:rate_group_id => @rate_group },
:with => “‘media_id=’+this.value’”
) %>">

I’m guessing that’s wrong since WebRick does nothign when I call that
function…

However this works…

<select name=“media” id=“media” onchange="<%= remote_function(
:url => { :action => :show_performer_categories, },
:with => “‘media_id=’+this.value’”
) %>">

So my question… how do you pass multiple parametes? media_id I can
get, the other I can’t.

thanks!
