This question already has an answer here:
I'm getting a really weird error from a file that I haven't changed at all during both these file creations. It was working fine and only started happening when I added the match for the passwords - then I deleted it to see if the error was resolved and the error was still there.
Also it appears in some of my text boxes with BR tags in between the words. however the script still does what its supposed to if I delete the errors from the text boxes and add some test data.
The guy in the tutorial I'm watching does not get these errors.
