Your code should never have worked.  You are putting the index of the
message into the display_type array!  Try this code instead:

        strcpy(DisplayBuffer+1, messages[frame.display_no[0]]);
        DisplayBuffer[0] = frame.position[0];
        Display(DisplayBuffer);

What you needed to know is that frame.display_no has an 8-bit NUMBER in
it. You specified this:

        unsigned char display_no[3];

which means an array of 3 unsigned characters.
