Report count have bug?

Ignition
1

I am using ignition report designer. inside it I create a table and browse a tag from database named this tag as A; The value of this tag, A, is always 0 now…

This tag is stored in database 1 hour once.

I group this table by day, so it means from Dec 1st to Dec 4th… I have 4 values… but why, when I try to use ’ @count.total.A@’ to count the number, which should be 4, the result is 0…

Can someone pls help… (I try another tag which the value is not 0… count function works)

The values in the @@ symbols are a kind of path through the dataset. If you column name is ‘A’, then you should be using a path like @count.A@ in your table to get the number of rows for column A. @total.A@ would sum all of the A values. This will work best in the Summary row of a table.
