additionally, that looks like an old version of the script, the current one (2018) is here (i think the link on boards page is old and this thread is tl;dr)
the images suggest a different problem, perhaps (uri not listed?), but try this first

fpsa, koogs - so sorry to have missed your replies! i got it working, thanks! koogs, your suggestion to try the current version seems to have worked. i'm not sure how i ended up on the outdated one before, but with the new script it immediately started working.
