Hi,

It may be a simple task, but I still can’t figure it out. I want to set the the check box field to null (no box chosen).

I try,

if ({check_field} == 'T'){
//some code
}else{
sc_error_message("text");
//uncheck the field
{check_field} = '';
}

and no success.

You may be able to do this in the Javascript settings area - Form Settings -> Javascript. Select the field and the action you want to control, then Edit. You can set the field property to something like document.F1.check_field[0].checked = false

You can find examples in the documentation - Content -> Form Applications -> Form -> Javascript
