Hi.
First a wanna start be saying that im a newbe at this so sorry if im stuped:)
I got some help whit this code, but the menusystem i try to make my self,as you all can see:)
But now i have run in to a problem i can fix:(
Im gonna try to explane the problem:
When i start the code, the first text on the lcd shows up = working
Then i can hit "A" or "B" on the keypad to get to diffrent menus = working
In menu "A" i can enter numbers and everything works good.
When i press "B" i get in to that menu BUT i cant enter any numbers, if i hit any key the menu goes back to menu"A"???
How can i get menu "B" to work the same way as menu "A"?
Thanks for any help!
