Comparing two files issue

Hi all, I need your help fixing an issue with this code. I am a newbie to UNIX programming and there is an issue with this code I am hoping you can help me correct.
I have two files (system_files with 8342 records and rules1.txt file with 762 records). My understanding from the script below, is the script will read the rules1.txt file and if it does find a match on system_files, it will skip the record on the rules1.txt file and not write it to the temp file. So the temp file should only have 7580 records on it. After I run the script, I am getting over 12 million records in the temp file with each file being dupluicated thousands of times.
Any ideas where this scripts is going crazy on me Smilie? Thanks

for z in `cat /test/mkamal/ge_ret/rules1.txt`
grep -v $z /test/mkamal/ge_ret/system_files >> /test/mkamal/ge_ret/temp

"1 user" or "10 users") v operating system version and build date (uname -v) OPTIONS
