This line has a run away string, and also you have variables inside ''.

Same for those lines, you have variables inside '':

    print "<input type=hidden name= 'index'  value='$i'>";
    print "<input type=hidden name='uname' value='$nme'>";

'' prevents variables being resolved to their values. If you want ' be part of your html, escape them like this:

my $a = 2;
print "\'$a\'";
