Inserting Variables

There are different data types for variables: "string", "number", "date", "Boolean" (logical values), "picture" and "barcode". The data type is important if you want to use variables as parameters in functions as they normally only accept certain data types. Thus you can only multiply a numeric value with a numeric value.

The "Variables and Functions" tab includes an overview of all available variables, an icon indicating the data type in front of the variable as well as the available functions.

You can filter the variables by means of the input field above the variable list.

To add a variable, double-click the variable that you want, use the "Insert" button or drag the variable to the editing line (also via the function list). The variable in question will be added to the editing line in the correct syntax.

Repeat the above steps to add more variables to your expression. If you want to have spaces between the individual variables, e.g. to separate FIRST_NAME and NAME, make sure that you enter this space in the editing line.
