        hi,

        when using a barcode scanner in a “module”, the mapping of the result parameters (“text” and “format”) to a struct fails with “Uncaught Path points to undefined field.”

        thx.

          Hello Klaus,

          the problem is that you are trying to move the data into a structure wich has no default values for the fields.

          You have to set a initial default value for all fields you want to access.

          Here you can find a little video showing how to fix this.

              What does that error message mean?

              I’ve mapped an integer field from an structure (global variable) to another int field from another global structure.

                      Hello Franz,

                       

                      you need to predefine your variable structure like i mentioned here.
