my record will be show as below:
Salesman Budget Item1 Item2 Total Variance
A001 10,000 1,000 500 1,500 (budget-Total)
for the "Total" column, i can use the existing column in cross-tab, but i need to add 1 more column after the "Total" column for count the "variance" and the "variance" column must display as last column in cross-tab
