I am new to Arduino and thought I would try and learn by modifying other peoples code and I’ve been ok with modifying code for other simple programs but this code seems to be a bit more complicated I have managed to change the sprites/Custom characters used but having trouble changing it to use all 4 lines on screen it works but only uses 2 lines still

I’m using Arduino to display text, but apparently it didn’t show up. Did I miss anything? I was trying to make the static texts stay at the start of the lcd and scrolling text scroll next to the static texts. I think the array is something wrong but I can’t find the error.
