Setting specific 404 error page?

I’m sure I’ve overlooked this, but my Google skillz aren’t too good today...

In Revo, how do you specify a particular page as your 404 page?

Sorry for the noob question...

system >> system settings >> then in the drop down filter by area put "Site"

Oh and double click on the number in the error page row. Set which ever ID of your resource you wish to use

Or search for ’error_page’.

Thanks. I knew it would be something simple. I had even searched for "error page" and came up empty. Ha.
