the way i get round this is to have a hidden row at the top of the defined field. I create a new column called sort. My header/hidden row i give the value of 0 and all other rows a value greater, (normally 1). In each column put a number, date or text depending what i want crystal to classify this feild
ie sort real real real real hidden row 0 1 1 1-1-01 abc First row 1 25.20 15.20 15-7-02 abccc second row 1 17.21 12.10 15-7-02 defff
no matter what data is in you first real row it knows that they are number, number, date, text. Then to bin the hidden row from your results go into the selection expert (or what ever its called) select column 1 'SORT' = 1, this the eliminates the hidden row from your results.
