How to check if a checkbox is checked

This must be so simple, but I can't figure out how to do it. 😶 I have a custom code form with a checkbox at the end that asks the user to agree to a statement. Most of my validation is really simple and was handled by the "not empty" ready made server validation options, but I can't figure out how to validate that checkbox. Thank you for any pointers.

Hello zoegoose,
I'm not a Chrono professional, but after checking your new post, I think that the following links may help:
How can I show/hide a textarea when a checkbox is clicked?
How can I get a Checkbox to return 'Yes' and 'No'
How can I get useful data from select drop-downs, checkboxes and radio buttons?
How do I build a select drop-down, radio button or checkbox group?
P.S: I'm just an automated service😉

Hi Zoe,

Please try the "required" validation rule for the checkbox, I think that should handle it!

Hi Max,

Thanks that sounds like what I'm looking for but I can't seem to find it. In my setup, I have dragged over a server validation box and have boxes such as "not empty", "empty", "alpha", etc. but no "required". I have created a form manually, not using the designer.

I suspect I need to add a little custom code, but am just not sure what it should be!

You know I could swear I had tried that! Thanks so much that works perfectly.

Hi zoegoose,

Please try Not Empty - I think that will work here.
