LED DOT MATRIX 64x16

Hello, I have recently purchased a 64x16 LED matrix, I have downloaded the zip file. And thank you guys very much!
But, I am have trouble editing the code to have text scroll the entire height of the display, I can remove the clock, the rectangle part, But I cannot seem to combine the upper and lower halves to form one display.

I am also very new to programming.

I need help please, or at least guidance into the right direction.
Thanks!!!
