Drawbox not drawboxing

[Sam]

Ifound a tutorial for adding a drawbox and thought it was really cool so I added it to my site but whenever I try to submit a drawing it says there's an error uploading the image or submiting to google form, does anyone know how I can fix this?

this thing uses PHP to work which neocities doesnt support unless u pay for it...Nekoweb gives that to you for free though!
nekoweb feels like a siren call to me because every nekoweb site i see is cool as hell LOL but im unsure what id put there or what benefit it would have to my site if i moved
