I just wanted to post that the problem has been identified. Crystal Reports 10, when using the Count summary in a crosstab table, will lock the format to an interger value. When the show as a percentage box is checked, it calculates the percentage, then truncates or clips the value to the right of the decimal point. This locks the percentage format into an integer display and the extra value is lost. Percentages will not add up to 100. I don't know if this is a known problem, or if there is a way to correct it in the options. I do know that reformatting the cell or the crosstab table will not work.
