Thanks Philip.

I forget which version of PHP allows you to do the following, it may be
4.0.6 or maybe 4.0.7 :
for ($a='a'; $a<='z'; $a++) {
print $a;
}
The way I get around this is by :
$letter = 'a';
for ($a=1; $a<=26; $a++) {
print $letter++;
}
It works or at least may easily work for your given situation. And on a
related note, in 4.0.7 the range() function will allow for :
$letters = range('a','z');
As currently it just allows for integers.
Regards,
Philip
