It's difficult to tell exactly what your 2 expressions are.  But I see 
forward slashes (/'s) all over that.  To use an s commad through sed is:

sed 's/searchFor/replaceWith/'

so if you have any "/" inside your expressions you need to escape them:

sed 's/search\/For/replace\/With/'

If you look at the error msg again "char 23: Unkown option", it's 
picking your 3rd slash in char position 22 as the final / delimiter for 
the s command.
