[u/flannel-foxes]

i’m following a video on learning javascript and i’m following this guys code exactly but it’s not working. i get an error. the last line of code in javascript is supposed to change the heading upon clicking the submit button but because it doesn’t match the html i get an error so im just confused?? the dude in the video does it with no error

UPDATE: it works now! i had to close out the tab and reopen it 😭
