Ok, you can do a few things differently
First, I see you are just checking al your snapmirrors.. What's your threshold? You should have a trigger point, who wants to look at all your snapmirrors.
Also, you can look into using the excel com object or piping it to an HTML page. If you search some of my scripts that will get you started
I see an issue. Replace 'n with 'r'n. 'n is a line feed, which by itself is ok for unix. I bet you are on a windows machine. You need a carriage return and line feed or you will muck up your text file, thus the chinese-looking characters.
