Help with codes to add 1 more shift register and add more to matrix LED

hi im working on 8x10 matrix leds , successful @ using guide

http://www.instructables.com/id/810-led-matrix-with-4017/

using 4017 , 74hc595

now want expand matrix 16x10.

i connected , worked added 74hc595 control second 8x10.

my problem want display text using both 8x10

im using code guide , modified think doesnt work

code: [select]


#define someshape    {b0100001001000010,b1110011101000010,b0100001001000010,b0000000001000010,b0001100001000010,b0001100001000010,b1000000101000010,b1000000101000010,b0100001001000010,b0011110001000010  }

      digitalwrite(clock,low);



   }
   }

  }
 }
}
}


void loop(){
 display_pattern(15);// calls display_pattern function , says int loop = 15(if more loop pattern whould scrrol slower).
}



problem 1 sure im doing declaration of bytes wrong.

i tried code using original outputs given 2 shift register identical no luck

doesnt work

in way not work?
