I'm trying to make a Wall Types Legend using the Legend function in Revit Architecture 2011.  I did the first wall type just fine, placed it in section, tagged the material, etc.  Now when I go to place another wall in a section view, it tells me the component is not visible in selected view.  Thoughts?!  They are both new construction phase, stacked walls.I've been going nuts trying to find the answer online and it is making me waste a ton of time at work (thank you Revit for helping my productivity... oh, wait...)

Any help is appreciated! 

Thank you,
