Create a Parent from Child using fields from Child then pass New Parent Record ID to Related Parent ID under Child to link them

Thank you Makes total sense, i will certainly check out the burger party. Unfortunately - For what ever reason the script isn't triggering - i click the URL button and wait, a few seconds later in console i get Evergage: Error decoding cookie segment: 100% but nothing more. Hopefully you can see what i am doing wrong...

-----------
1. To confirm, button has:
"javascript:" &  
"var F3='" & [Record ID#] & "';" &
"var F72='" & [Related Project] & "';" &
"var F77='" & [Related Site] & "';" &
"var F120='" & [Description] & "';" &
"var F84='" & [Project - Related customer] & "';" &
"var F100='" & [Date of Issue] & "';" &
"$.getScript('" & URLRoot() & "db/bm3kptpzr?act=dbpage&pagename=AddWR.js');void(0);"
-----------

2. The href for the button shows per below in inspect:

javascript:var F3='2';var F72='7';var F77='3637';var F120='2';var F84='1';var F100='';$.getScript('https://rosjohnston.quickbase.com/db/bm3kptpzr?act=dbpage&pagename=AddWR.js');void(0);

-----------

3. AddWR.js has the below code:

var dbidSOW = "****";  var dbidWR = "****"  var apptoken = "****";    $.ajaxSetup({data: {apptoken: apptoken}});    $.get(dbidWR, {    act: "API_AddRecord",    _fid_48: F72,    _fid_132: F77,    _fid_7: F120,    _fid_147: F84,    _fid_77: F100  }).then(function(xml) {    console.dirxml(xml);    var WRrid = $("rid", xml).text();    console.log(WRrid);    $.get(dbidSOW, {        act. "API_EditRecord",      rid: F3,      _fid_114: WRrid    }).then(function(xml) {      console.dirxml(xml);      //document.location.href = ...    }); 

});
