Why if there are are two ‘popupWindow = window.open’ scripts does the second script’s argument control both?

I have two scripts for popup windows. In all cases the arguments for the second script is controlling both. How do I fix this?

    <script>
    function firstPopup(url) { 
    popupWindow = Window.open(url,'popUpWindow','height=300,width=300,left=200,top=200,resizable=yes,scrollbars=no,toolbar=no,menubar=no,location=no,directories=no,status=yes')
}
    </script>
    <a href="JavaScript:newPopup('bitcoin.cfm')" style="color:black">Here.<a href="JavaScript:newPopup('contactpri.cfm')" style="color:black"></a></script>
 <a href="JavaScript:newPopup('bitcoin.cfm')" style="color:black">Here.<a href="JavaScript:newPopup('contactpri.cfm')" style="color:black"></a>

Text and other stuff here.

    <script>
    function newPopup(url) {
    popupWindow = window.open(url,'popUpWindow','height=700,width=800,left=10,top=10,resizable=no,scrollbars=no,toolbar=no,menubar=no,location=no,directories=no,status=yes')}
    </script>
    <B>If you want to Contact US <a href="JavaScript:newPopup('contact.cfm')" style="color:#062689;">click here.</a></B>`

Both scripts do work. It is just that the second height and width are overwriting the first argument.

What do I need to change to make them used their own arguments? I have no idea have to differentiate the scripts to make this work
