Hiding 6 text fields based on whether one check box is checked or not

[#1]

Hello,

I want to have 6 fields that both turn on (become visible) and become required when I check the check box to their left on the form.

All the fields are on the same page and are all text fields.

The On Value is set to "Yes"

The Off Value is set to "No"

Cheers,

Wes

This is what I have so far.

if(xfa.ONE.FORM.ASSAY.rawValue== true){

  //xfa.ONE.FORM.CO_ASSAY.presence = "visible";

}

else if(xfa.ONE.FORM.ASSAY.rawValue== false){

  //xfa.ONE.FORM.CO_ASSAY.presence = "hidden";

}
