Error in custom script (print form)

I don’t know what happened. But, this is happening after I play with printing form.

Please help me!

Have you made any changes to code? Or have you added any custom script?

I already fix the problem. It is because I forgot the semicolon inside the custom script. But still, this is weird as the error not meaningful. Thanks for reply @saurabh6790

A missing semicolon in JS isn’t a problem to execute the script. Are you sure there was no other issue?

I don’t really know what the cause of this error. But, it is gone after a semicolon added inside the custom script.
