Forums Scripts & Popups Ban through X or Channel Mode

Hi judge2020, I do like the idea of having the script read a list, however, when I add this line...

if ($address isin $read(bannedhosts.txt)) {

the script does not seem to read or react to it. I did create a txt file using the same name, and I did write a couple addresses to it so that I could trial it, but to no avail.
