Loading External Files Into A List - Proper Set-up

[liwenna]

Confusement I see!

Something is terribly off in the part regarding "files/listsubject" &
c.GetAttrib("subject") & ".txt"   and/or the
listsession" & c.GetAttrib("session") & ".txt"  . The file that I took
the code from actually uses an attribute called 'group' but as that is
not a standard attribute in e-prime I thought that I would better
replace it by session of subject and apparantly I didn't choose
consequently ;)
