    Help with Validation Formula



      Help with Validation Formula



           I need to validate that a field YBImage has only 5 char the first char must be either A B C or D and the remaining 4 char must be numeric.

           I know I can check the length with

                   Length ( YBImage) = 5

            and I can check the total contents with

              Filter ( YBImage; "0123456789ABCD"=YBImage

           from there I am lost.  How do I check to be sure the alfa char is in the first position?
