Calculate a total sum of all Database Rows Follow

I take it you are using the table function in a BarTender template. I am not sure if there is a way to do this more easily but the only way I can think of is reference each text object individually and add them together and so the text object in the bottom line of the above grid is a VB script routine:

Value = Int(Format.Objects("Text 1").Value) + Int(Format.Objects("Text 2").Value) + Int(Format.Objects("Text 3").Value) + Int(Format.Objects("Text 4").Value)

Hello,

My database select returns more than one row.
I now want to calculate a total sum over all rows from the Weight field.

I have 2 options. Both have a problem in my opinion.

1. i have started an attempt with the table object. Here I have the aggregate functions like sum(). But there I can't pass a where condition in the database select.

2. i have a report with page template and groupings. There I would not know how to calculate on groups sum and on total sum.

Okay, It wasn't clear from your original message that you were using Page Templates and records per page so will have a play and see.

I remember, sometime ago with multiple labels in a batch, where we did something similar but this was individual labels and not with a page template.  

Rather than use the page template, you could use the Records per Item setting in the Database setup:

With this each field it added on the label individually and you can reference in them in VB directly:

with VB like this in the calculation field

Value1 = Field("numbertest.numbertest.f3")
Value2 = Field("numbertest.numbertest.f3 [2]")
Value3 = Field("numbertest.numbertest.f3 [3]")

Value = Int(Value1) + Int(Value2) + Int(Value3)

(Needs a bit of tweaking as I get a type mismatch warning but it does work)

Hopefully this may help
