Copy a text field based on checkbox value

[trf22]

I would like to copy selection based on if a check box is selected. How can I do this. I have attached a screenshot of what I am wanting. 

The user will slect the time they need our service on Monday. I have a box they can select if it is the same all week. If so I would like the rest of the days to auto populate to match monday. 

I want the same thing for sunday.

Here is a basic script as 'Mouse UP' action of checkbox:

if(event.target.value != "Off"){
this.getField("Tuesday").value = this.getField("Monday").value;
this.getField("Wednesday").value = this.getField("Monday").value;
this.getField("Thursday").value = this.getField("Monday").value;
this.getField("Friday").value = this.getField("Monday").value;}

Thank you so much. I'm new to Java. This is a very dumb question. Where do I put this?

Also do I post the entire script you sent me?

Would it be the same for the 2nd checkbox? If they check the box under saturday I want it to autopopulate sunday.

I tried it but I guess Im doing it wrong. Not sure how to make it work. I attached the file if that helps.

Script is in checkbox → Properties → Actions Tab → Select trigger: Mouse UP → Select action: Run a JavaScript.

Here is your file with scripts added:

This is perfect. One last thing. Is it possible to make the checkboxes abvoe the other days check as well? If so I would like them to be checked if they select same all week or same saturday and sunday.

Sure, do you also want to add if checkbox is unchecked to revert field values to default?

I'm not sure what that means. If the check box is unchecked that means the user should fill out each day.

This is PERFECT. Thank you. I want to learn how to do this.
