In this window we can create our expressions, which will be evaluated later and forwarded towards the selected output module.
Using the Expression Name field we can name our expression (this data serves as an individual identification, so we cannot give the same name to two different expression within a group).

In the bottom third of the screen we can find the list of variables added. By clicking on the right mouse button the variable can be inserted into the text of the expression.

In the "Mathematical expression" field we can specify our expression. We can refer to the values of variables by their names. We can use the mathematical base operations, or any valid Visual Basic .NET function or expression (Mathematical operations and functions in expressions).
You can find more help about expression at our web page. (http://www.konsys-international.com)

The parameters placed in the "Public text" and "Public variable" fields will appear in the pages of the output report and the exported document as expression attributes.

Not only the value but other features of the variables can be given in the expressions as follows:

Following the name of the Variable put a dot and the attributes of the variable will appear.
