-Lost,

Thanks, that worked well.

So that i can learn something and not have to ask a question in the same
context, again, could you walk me through what these lines are doing:

for($i = 0; $i < count($fields); $i++)
{
for($j = 0; $j < count($badchars); $j++)


I understand that I have to traverse through both arrays, but I'm not sure
what you did in the above lines.

Later,
