i used datatable as datasource, datatable contains 4 columns having boolean data type

i want to count the no of true values in the column.

i m nt using any group by clause.

i used this formula to count true values for four columns

numberVar Zero=0;
if {viewrptattendance.isPresent} = True then
(Zero:=Zero+1)

bt facing problem in its result as it did nt give right ans or it did nt count correctly.

i have read this type of counting topic here in this forum, i think that my problem is about grouping options

wt do you say?

Every time you declare the variable you are resetting it to zero. Just declare it like this:

NumberVar Zero;
