buttons dissapeared in dvdlab

[GETSIDEWAYS]

im authoring my first dvd using dvdlabpro. i have a main menu with a motion clip backround with audio, and 2 chapter menus with 6 motion clips on each chapter menu. i put a title and a play and chapter button on the main menu. and i labeled each chapter on the chapter menus. when i test it in windvd my title and 2 buttons are missing on the main menu and all my chapter labels are missing on the chapter menus. what am i doing wrong? thanks

You need to check the mapping. The normal state for your link items must be completely transparent, which is why you can't see them. Set them to a solid colour.

sorry to sound dumb but how do i check mapping and what is it? also i dont understand the transperancy thing. my slider is all the way to the left. when its to the right the text dissapears. and my text is already set to black. is that what you mean by a solid color? thanks
