Show the code you have that is not working. As far as the message goes, if you are using button symbols you could place the message in the over frame for each button--that way it will appear when you hover without the need for any coding. Alternatively, you could have a movieclip that is triggered to appear (_visible = true) when you rollover a button for which the button code assigns the message for the movieclip to display
also i have a huge map and i cant make it fit the whole screen so is there a command thatll make it so they can scroll over a border and itll move the screen in the direction the cursor is in?
If that code is attached to the button, and is not on the timeline, that should be (adding 1 quotation mark and a comma)...
If the code is on the timeline (the better approach) then that code will not work.
As for your other question, start a new posting. You can't move the screen... you have to move the map.
