I went to the URL and it appears to be working fine. Have you already fixed it?

If not, I think it may be a combo of problems between the lines:

name1=`echo $slice|cut -d+ -f1`
name2=`echo $slice|cut -d+ -f2`
name3=`echo $slice|cut -d+ -f3`
name4=`echo $slice|cut -d+ -f4`
name5=`echo $slice|cut -d+ -f5`
name6=`echo $slice|cut -d+ -f6`

and the $? = "0"

I think if you are doing a cut -f6 but you did not feed it a 6th name, name6 will be set to nothing. When you do a who | grep > /dev/null, this may return 0 on some systems because it runs but does not produce output. I tried on Sun and actually got a return code of 2 plus a STDERR about the correct usage of grep. You could simply add a test to the loop that checks to see if $name != "". If it doesn't, then process the username, otherwise just exit because you know if name3 is blank, name4,5, and 6 are aswell.
