Says it all!   
  
 The steps I took:   
 Project A has:   
 - var: BuildFailedStamp   
 - GetDateTime action that puts system date into this var   
 - Write File action that includes the %BuildFailedStamp% var in the body of the text being written.   
  
 Project B has none of that.   
  
 Open project A and B concurrently in two sessions of FB   
 Copy paste the two actions above from A to B   
 Run B   
  
 Notice that the GetDateTime action succeeds… but the Write File action fails due to the non existent VAR

Thanks, fixed for next build. I’ll post here later today with a build which includes the fix.
