If I tick "check box", other section become mandatory

[hyung2x]

As topic, if I tick on the check box, how to set the section/field become mandatory? If untick, the section/field will become Read-Only.

Example

Check box: Education_Planning

Field to mandatory 1: Name_of_Child

Field to mandatory 2: Age

Can I use this script?

if (this.rawValue == "01"  || this.rawValue == "02" ) {  //01, and 02 are LIC codes for and On and Off

util.enableField(Name_of_Child.somExpression, true);

color.markRequired(Name_of_Child);

}

else{

          color.markUnRequired(Name_of_Child);

          util.enableField(Name_of_Child, false);

}
