There is a conceptual problem in this line near the beginning and the end…

…and in this line near the beginning and the end.
The same problem leads to a program logic problem (although not a syntax
error, which is why it is not so easily spotted) in the following line:
> RegExp("\ \b"+escapeRegExp(find)+"(?=[^a-zA-Z\*])",'gi')
It is too bad that the OP was posting with an invalid “From” header field
via a troll server, so that is all that I will say about it until at least
the former changes. Then again, they may have found the problem already.
