I am trying to make it so that the user can not enter any information into a
cell where the value for it's criteria is 0. For example I am doing Special
Project Hours with a Special Project Hours and Code column. For any Special
Project hour column that has a number less than 1 I don't want the user to be
able to input anything. The trouble I am having is my Special Project Hours
column is a dropdown list that I created with a data validation rule. Any
help would be greatly appreciated.

Thanks in advance
