I want to define the output in the template depending on two given values.
I thought I have to do this by a template member function, but I don't know how to pass two template vars (e.g {var1}{var2}) to one member function.

The member function should return a string depending on two passed boolean values of var1 and var2. That means, the output of that template variable has four possibilities.

Would be nice if anybody can give me an advice - thx
