Do not allow checkbox to be unchecked once chosen.

[Kathy409]

I have a "Statement of Understanding" that we want them to check once they read it.  However, once they check it, I want it locked so they cannot uncheck it.

Is that possible?

Hello @Kathy409,

Can you post an example of your form?

If you use checkbox you can use this script as Mouse UP event of checkbox:

if(event.target.value != "Off")
event.target.readonly = true;

Or you can simply use radio button and change button style to 'check' so it looks like checkbox, because radio buttons once checked can't be unchecked.

Thanks! It works like a charm.
