1: You forgot the parentheses for the function.

2: You didn't define 'player'.

3: I recommend you to start from the basics of Lua.

function saytext(player, command) 
     outputChatBox ( "[ "..getPlayerName(player).." ]: #ff0000Hello!", root, 255, 255, 255, true) 
end 
addCommandHandler ( "hi", saytext )
