Hello everyone

We are having some issues with this exception since we are generation all information dynamically and don't always have every parameter in hand

Is it possible to make/have an optional tag/variable inside de XLS?
I saw the IMarkersDesigner interface and that it is possible to use the enum UnknownVariableAction, but I am not sure if this is the right way to do this or even how this is supposed to work.

Any help is appreciated. thanks a lot.
