I’m using a “ClearCase Run Cleartool” action but the command I’m trying to run uses a _-fmt “%u %Rf\n”_ parameter. When I run the action it fails with a error “_Error expanding Arguments : Variable : u, - does not exist!_”.  
  
Can I escape the %'s so they are not seen as a variables?

Hi Wayne,  
  
You can double-escape %s as %%. FinalBuilder will expand them to a single %.
