Calculating checkboxes choices | WordPress.org

[ad_1]

Hey guys. Great plugin, I’m really impressed – so many features!

However, I have one question. Is it possible to calculate the number of options that the user chooses in the “checkboxes” field? Let’s say, I have 10 choices in checkboxes, the user selected 3 of them. I need to use this value (“3”) in further calculations, so how can I do that? Thank you in advance!
