i want it to do like this.
_____________ _____________ _____________
I message1 I when pressed down --> I message2 I and down agien I message 3 I when pressed ones more back
I message2 I I message3 I I message 1 I to picture one.
______________ _____________ _____________
i want do be able to do this the reverse way whit up too.
i have made a fast sketch i know the syntax is all messed up but i think u understand, see it as a mind map
if down button pressed
else if up button pressed
then my ide of z is that depending on the what x is it going to put different text in z. like
if x= 1
else if x=2
its the last part with z i cant solve.
is this possible or how do a solve the problem? i have tried to google it but i dont know what to search for.
