I might be wrong, but from all my tests, it seems if you put a string variable between quotation marks it doesn't work. Which might be by design, but I've not seen it this way with anything else that accepts strings (setting text in a text box, etc).
I do not have a capx to load right now (out the door for christmas eve), but can later if it seems i'm the only one having the problem.

edited post say variable, sry about that, was rushing out the door. using a specific name works fine, it's only if you use a string variable, like "layoutName" vs layoutName.
"layoutName" - doesn't do anything that I can tell, and doesn't go to any layout.
layoutName - reloads the current layout
