I will answer your question using the JavaScript example the Max Wyss posted in the following thread a long while ago: https://answers.acrobatusers.com/show-hide-multiple-fields-based-on-a-check-box-and-then-make-them-show-again-q299956.aspx
You need a mouse up action javascript in the "Nofee" checkbox.
In edit mode, right-click on that checkbox field select Properties from the context menu.
This will open the Checkbox Properties dialogue box where you will then click on the "Actions" tab.
Follow the slide below:

After you've clicked on "Add" use the code I am posting here for you (or modify as desired):
if (event.target.value !="Off") {
this.getField("CardYes").display = display.hidden;
this.getField("CardYes").checkThisBox(0,false);
this.getField("CardNo").display = display.visible;
this.getField("CardNo").checkThisBox(0,true);
} else {
this.getField("CardYes").display = display.visible;
this.getField("CardYes").checkThisBox(0,true);
this.getField("CardNo").display = display.hidden;
this.getField("CardNo").checkThisBox(0,false);
}
Click close to exit this dialogue box , and you should be good to go.
