Hello Michael5119,

has not "onclick"event,you can use

<input id="Checkbox1" type="checkbox" onclick="forRentClicked(this)"/>

to replace it.

Set location=no,Javascript example code:

window.open('test.html','newwindow','height=600,width=800,top=190,left=350,toolbar=no,menubar=no,scrollbars=no,resizable=no, location=no,status=no')
}
