Every time I open the scripts in Functions, I see "&&" are replaced with "&&". But if I save the script, "&&" cannot be accepted; so I have to change "&&" back to "&&". However, if I reopen the script, it's still "&&". 

In addition, if "&nbsp" is involved, the script may give like this: " ". 

Previously it functioned OK so I wonder whether it's a new bug. 

Thanks!
