Hi, i'm Rafael Ratier and i'm from Brazil

I can't program my LEGO Mindstorms to do what its written above

I want to do this:

A menu with 3 opitions:

2000, 4000, 8000

Starting with 8000, if we press the right NXT button it will become 2000, and if we do it again it will become 4000. One more time it will me 8000 again. Starting with 8000, if we press the left NXT button it will become 4000 and if we de oit again it will become 2000. One more time, if we press the left button it will be 8000 again

It's a loop with 3 opitions. Choose one and press Orage NXT Button

Once you have pressed the Orage Button, the cauculator starts

For exemple, you choosed 8000. Now each time you press the right button it will become 8050, 8100, 8150... If you press the right button you'll add +50 to the orignial Number. The same heapens with 4000 and 2000 ( 4050, 4100,4150.....2050,2100,2150.....)

And also, each time you press the left button it will become 7950, 7900, 7850... If you press the left button you'll subtract -50 to the orignial Number. The same heapens with 4000 and 2000 ( 3950, 3900,3850.....1950,1900,1850.....)
