I have a range of cells A1:A20 that has data validation and must be a double letter code contained in a list.The list is ALL Upper Case( must be Upper case to link correctly to another program).The problem I have is that some users will type the code in the cells rather than choose from the dropdown list, which results in an error when the other database imports it in.Is there an option in the validation that requires the user to actually use the dropdown list?As it is now the user can use the dropdown list or simply type in a code contained in the list whether upper case or not. Hope I'm making the issue clear enough to get help with this.Perhaps I could enter a Code that would prompt the user to use all Uppercase if it sees any lowercase letters in range A1:A20
I appreciate the help.
