Thanks for your quick help! Unfortunately, that didn’t help. The same error keeps popping up in the Developers Tools console from Chrome. I used the following shortcode to add the field:
[signature* autograph 300x200]
It gave the same error as my previous post. It says there’s a mistake with this.
// Submit Event Listener
submit.addEventListener("click", function(){
if (!signature.isEmpty()){
input.value = signature.toDataURL();
}else{
input.value = "";
}
}, false);
If you need more information I’ll do my best to give it to you.
