Great! I was looking into the map function. Have found this at another threat.
Thanks. This will do.
I have one last question, if I may 
When it shows the value on the display and I change the value it somehow mixes with the previous printed. Example: value is 1023 and i low the value to 0050 it will leave the 10.. or write lower number. Somehow the display should refresh at each value change, so the previous one is gone.
don't now if you get what I mean. It is mixing all numbers and it makes it impossible to read the actual value properly. Some sort of clear screen or refesh function for this?
