Hi, thanks for the advice, but I have one question, is that possible to get checkbox status, if is checked or not ? I have a big problem with that

In case anyone's wondering about this, this snippet is at https://docs.gravityforms.com/gform_pre_validation/ so you could ask Gravity Forms' support about "their own" snippet if you have follow-up questions.
