Larger Numbers!!!

How could I keep the numbers in column D>C>B>A? Also, I have already used data validation to keep the numbers in columns ABCD with a range, therefore data validation wont allow me to use it twice. Will VBA work? If so, what is the code? Thanks much!!!

Try this
Data validation>Custom:
=AND(B3>A3, B3<C3, B3<maxrange, B3>minrange)
With custom you can create a very long validation formula.
