Thanks to both jerry and racke - [item-modifier quickorder] works just 
fine! I'm not too sure how these modifier things work but am i right in 
thinking that i could somehow use the form submission process to mark 
quickorder=1 instead of the nasty bit of perl i currently have? Also can 
somebody explain the difference between AutoModifier and UseModifier?

thanks
